Featured Listing: 1974 Laverda 750 SF2 for Sale

Tad Diemer 0

Today’s Featured Listing Laverda 750 SF2 is definitely more of a classic sportbike, but it’s definitely rare and such an icon we couldn’t help but publish! For fans of the site who aren’t really familiar with low-production Italian bikes of the 1970s, you could probably think of Laverda as “the Lamborghini of motorcycles,” since they also got their start building farming machinery. Bikes were added to their repertoire to help supply the post World War II need for cheap transportation with early examples clocking in under 200cc. But Laverda knew that, in order to compete with rivals like Triumph and sell bikes in the USA, they would need to expand their range to include bigger, faster machines.

Their first big bike was a 650cc parallel-twin that was introduced in 1966 and then enlarged to 750cc’s in 1968. It was powerful, with 60hp and fast, with a tested speed of over 100mph, no slouch for a stock motorcycle of the era. It was also legendarily overbuilt with five main bearings in the twin-cylinder engine, and every part not designed and built in-house was chosen for quality. The “SF” in the name stands for “Super Freni” or “super braking,” a reference to the huge twin leading-shoe drum brakes fitted to the original machines, although by 1974 the system had been updated to a pair of Brembo calipers and discs.

The Laverda SF wasn’t light or nimble, but it was very stable and proved successful in endurance racing when kitted out in SFC or “Super Freni Competizione” form. As rare as they are, they’re pretty reliable for vintage machines, relatively simple to work on, and parts are apparently available to keep them running.

From the Seller: 1974 Laverda SF2 750 for Sale

As seen on a recent cover of Classic Bike Guide. This Laverda was acquired in 2012 from the second owner (I believe) who did extensive restoration on the bike including a complete engine rebuild from renowned Laverda expert Scott Potter. This bike runs as good as it looks with no issues.The original Nippon Denso gauges were rebuilt and function perfectly. The original polished Borrani Wheels were laced and trued by Buchanan’s, the rear shocks have been updated to Hagons, the front forks have been upgraded to Works Performance dual rate springs etc. The bike has been restored using either original NOS parts or correct reproduction parts mostly sourced from Columbia Car & Cycle in BC Canada. Even the two keys for the seat storage box are included.The bike is complete and ready to ride or show.

It is original with a few exceptions that I am aware of as noted: the Euro rear tail light; (the original large US tail light is included with the sale); the front brake rotors have been drilled; the original foot pegs have been replaced with modest rear sets; the horns work great but are not original. The pictures tell the rest of the story.  It has the original exhaust with the crossover pipe and it even has the rare “Conti” stamped exhaust brackets. This Laverda comes with the complete correct tool kit in the correct stamped Laverda tool bag. It also has a new battery. Included with the sale if the reserve is met are the optional  solo seat, a front and rear fender painted to match the bike, an optional left foot shifter kit, (I have not used this) Tommaselli Clip-Ons, and a considerable treasure trove of literature including 2 copies of Tim Parker’s Laverda Twin and Triple Repair Guide (one original and one revised). Two period correct (if tattered sales brochures), a copy of Nolan Woodbury’s extensively researched article on the Laverda SF/2 twins as it appeared in the November 2016 issue of Classic Bike Guide, a Laverda Spare Parts List for the SF2.  I will also include related vintage articles that I have collected on this Laverda model. They are from the 1974 issue of Cycle Guide with a cover story on the SF/2, the 2013 issue of Classic Bike Guide with a cover story on the SF/2, the January 1992 Bike Journal with a cover story on the SF/1and various other articles on the SF/2. Please note that this bike is a right foot shifter. 1974 was the last year for the right foot shift Laverda SF/2. This bike is being sold as is with no guaranty or warranty. The bike is currently registered and titled in California.  

A $1,000 deposit is due within 48 hours of purchase with the balance due in ten business days. The bike is available for inspection in the Rancho Santa Fe, San Diego, CA area. Inspections can be arranged with advance notice. I can assist in helping the shipper of your choice. The bike can be stored indoors for up to 90 days as long as the bike is paid in full and insured by the buyer. I can also deliver the bike in an enclosed trailer (for a fee) if you are in the vicinity. I reserve the right to end the auction at any time as the bike is for sale locally.  

The days of reasonably-priced SFs are long gone and nice Laverda twins are not only hard to find, but command high prices when they do come up for sale. While the competition-oriented SFC sits at the very top of the Laverda twin hierarchy, the SF1 and SF2 are much more practical motorcycles, as the SFC is literally a race bike with lights and mirrors tacked on almost as an afterthought. This example is about as nice as you’re ever likely to find, and it’s even appropriately Laverda-orange. Bidding on the eBay listing is up to over $10,000 with several days left on the listing.

Two-Stroke Hooligan: Cali-Titled 1989 Yamaha TDR250 for Sale

Tad Diemer 5

This bike got me excited because Practical Sportbikes has been doing a project Yamaha TDR250 over the past few months, and up until I saw it, I had no idea the bike even existed. You say it’s not a sportbike? I say if it’s in Practical Sportbikes, it qualifies! So what exactly is a TDR250? Well basically it’s the parallel-twin from the TZR250 in a supermoto-style machine, with different tuning to suit the bike’s new mission.

Weight was right in line with the TZR at just a shade north of 300lbs dry, and the claimed 50hp is pretty close as well, helped by the same Yamaha Power Valve System. The supermoto set up means you’d probably lose out to a TZR on track, but the TDR would probably be faster just about everywhere else. Certainly, the riding position would be a damn sight more comfortable than the racer-crouch required for the TZR…

This particular example has obviously been enthusiast-owned, and the listing includes details of recent engine work, updates to the suspension, wheels and brakes, although he doesn’t mention where he got that banana swingarm. It’s not really necessary here with the undertail pipes but it does look pretty cool. Maybe it came from the RS250 that donated the rear wheel? This TDR is not perfectly original or in pristine cosmetic condition, so it won’t be of much interest to anyone looking for a museum-quality collectible, but these really aren’t all that valuable yet anyway in the rest of the world. The main thing driving the price for this one is likely the novelty and that very desirable California title.

Japanese and Canadian market bikes, never imported to the states, a lot have ended up in the United Kingdom where new parts and spares are readily available.

Bidding is up north of $5,000 with just about 48 hours left on the auction. In one of its home markets, I doubt it’d ever make near what it looks like it will sell for here, but I bet two-stroke junkies are leaping at the opportunity to pick up this very funky little machine, especially in California where little smokers have a pretty rabid following and road-legal grey market bikes from this era are hard to come by.

Featured Listing: 1989 Kawasaki KR-1R!

Mike 37

It may take you a little bit to pry yourself away from this first picture. It’s OK, I’ll wait a moment. Yes, that is an honest-to-God, freaking *original* Kawasaki KR-1R. The rarest of the rare of the quarter-liter smoking set has arrived, and this is your chance (and likely your only chance) to score one of these “what lies at the end of the rainbow” sort of machines. KR-1 examples are few and far between these days. The “R” spec – as it does with all other mega cool bikes with sporting intent – kicks things up a notch into crazy uber collectable mode. With KR-1 models coming across our pages so infrequently, it should be no surprise that the one and only KR-1R seen here on RSBFS was over 6 years ago (and based in England). Today, we are thrilled to bring you what must be one of only a handful of KR-1Rs that live here in the US – and this one is titled for street use.

You might wonder what’s the big deal about the KR-1R. Visually, it differs little from the lesser KR bikes. They all share the same parallel twin, reed valve inducted 250cc two stroke power plant. This motor, while not the trendy v-twin variety, has the distinction of being the most powerful of the 250cc smoking set. When it comes to bragging rights, the Kawasaki hits hard. Fun fact: A KR-1R holds the speed record at Bonneville for 250cc production motorcycles. The KR-1S is slightly different from a base KR-1 by color scheme and wheels. There are also bits that you cannot easily see, such as improved suspension components and chassis modifications (all KR models have an aluminum chassis, naturally). Take the KR-1S, add larger carbs for even more power, bolt on a close ratio gearbox and stronger clutch springs and you have one of the approximately 180 KR-1R Kawasakis in the world. It goes without saying that the KR-1R has a unique paint job with its nomenclature very, very clearly stated. All “R” model bikes were domestic (Japan) only machines.

From the seller:
The bike came from a Kawasaki collector in Japan. Motor is all stock. Stock carbs,
stock airbox, stock heads, ect all confirmed OEM Kawasaki. Fairings 100% OEM.
Windshield appears to be OEM. Two Keys.

Previous collector has cosmetically customized this KR-1R with Kawasaki OEM green
front fender, Beet rear sets and Beet exhaust and mufflers. Some suspension
components have been polished.

The bike has been professionally resprayed. Being a Kawasaki dealer with ties to
Japan, I was able to source OEM decals and correct paint codes. The paint job was done correctly. You may notice, The lower air vent was not blacked in like you see other KR-1R’s on the internet. The green and black paint lays over the air vent with a 50/50 split like it came from the factory.

All three brake calipers were sent to Powerhouse in England for complete
refurbishment. Powder coated, new seals, pistons, pads, ect. because they were old
looking. I have all the original brake parts that go with the bike.

More from the seller:
Bike has newish tires, Dunlop GPR’s, new brake fluid, new coolant, new oil, new
battery. Bike runs flawless at sea level and a little rich at my 4500ft elevation.
Bikes runs perfectly.

Bike comes with Utah title and is titled as a street bike for road use. I am looking
for offers over $20K – highest offer wins the bike. Potential buyers can contact me via email with offers. Only 180 bikes were made and this one is a very low serial number. Complete Serial number won’t be published.

Price: Accepting offers over $20,000

Deadline: July 1, 2017

Contact: rmurangemasters@aol.com

If some of the pictures look familiar, you will notice this is indeed the same Utah collector (and Kawasaki dealer) that recently thinned out a number of exotic machines (some purchased by RSBFS readers!). Gary states that this KR-1R was a crown jewel in his collection, but it is time to move on. There are A LOT of pictures, and I’ve included as many as possible. If you are serious buyer and there is something that you want to see, ping Gary for more details. Word from our readers is that Gary is great to work with and the purchased hardware shows up looking as advertised. That is good to know, especially when dealing with what may be the only US-based KR-1R with a street title.

Values are hard to come by when so few examples change hands, but I can assure you that $20k is a bottom dollar bargain number when it comes to a clean and sorted KR-1R (if you can even find one). This bike looks fantastic, and is one of the more rare models you might hope to see on RSBFS this year (or the next). So if you have a spare kidney laying around that you’re not really using, NOW is the time to reach out to Gary (rmurangemasters@aol.com) and make a deal. Good Luck!!

Vintage Racer: 1970 Yamaha TR2 350 for Sale

Tad Diemer 5

Introduced in the late 1960s as an over-the-counter racebike, Yamaha’s TR2 was based on the road-going R3, and was extremely popular among privateer racers of the period. At just 253lbs dry, the bike was lightweight and, with a nearly square 61mm x 59.6mm bore and stroke that worked out to 348cc, the little air-cooled, two-stroke parallel-twin put a claimed 55hp through a five-speed gearbox.

The huge drum brakes at both ends seen here were difficult to adjust correctly and are obviously not as effective as discs that would have likely been fitted to period racers as soon as they could get their hands on a set, but look very shiny!

From the original eBay listing: 1970 Yamaha TR2 350 for Sale

Restored to an excellent condition. Matching numbers. This very rare racebike have been completely overhauled with a lot of brand new parts as new cylinder barrels and pistons and an overhauled crankshaft, new Koni shock dampers, tires etc.

Transport can be arranged to most EU countries as I can deliver it by myself for actual costs for petrol and ferry tickets and, depending of distance, overnight costs at a cheap hotel. Transport outside Europe must be arranged by the buyer himself. I will make it ready for shipping with a crate and good wrapping.

Currently located in Sweden, this bike is in extremely nice condition, considering the age and the hard life most racebikes have endured, and appears ready to run or for display. Starting bid is $9,900 with no takers and very little time left on the auction, so move fast if you’re living room needs redecorating!

1999 Laverda 750S with under 1,000 miles !

Donn 4

In the late 1990’s Laverda was re-incarnating their past glory and made some of their best big upright twins and triples, before being purchased and then shuttered by Aprilia.  Presented here is a rare yellow and very late 750S, sparkling with only 994 miles.  Could be the nearest thing to a brand new Laverda out there.

1999 Laverda 750S for sale on eBay

 

The basis of the 750S is the company’s signature twin, but updated with 4 valves per cylinder, a balance shaft, fresh air intakes and Weber fuel injection.  The powerplant inspired reviewers to put the excellent twin-spar alloy frame through its paces, and the premium Paoli suspension was worthy.  The company was known for not scrimping on components, as the gold line Brembo brakes and Marchesini wheels testify.  The fairing favors the solo rider with a snug seat and step up for the pillion, and the upturn of the dual exhausts is delayed to accomodate the rather rear-set pegs.

 

Evidently on display almost since new, this 750S still needs its break-in miles.  You’ll have to lift the seat to add fuel, since the 750S was an early convert to underseat fuel and high airbox.  Finishes are unmarked and somehow the bike escaped the garage elves that usually plot a tipover or dent.  The seller relates that he is the second owner, and keeps it simple in the eBay auction:

1999 Laverada 750S with 994 original miles (1598 Kilometers) in like new condition no damage ever. Temperature and humidity controlled environment, on battery tender and covered. Starts and runs strong. Everything works, no leaks. Pictures speak for themselves.

 

At the time, European manufacturers were reeling from eastern competition, and couldn’t hope to turn the clocks back.  Like many, the Laverda response was reverential to past glories, and a competent if not class-winning performer.  Great design and top components make for a worthwhile experience, though at this point one would have to be mindful of the parts availability question.  But if you have the bug for a classic Italian, why not pick one that looks showroom new ?

Hat on Backwards: 1989 Yamaha TZR250 3MA for Sale

Tad Diemer 4

Competition between the Japanese manufacturers in the 250cc sportbike class was fierce, with each trying for some small advantage in terms of performance, given the limited displacement and government-mandated power cap. On paper, they all seem to follow a pretty standard template: a compact two-stroke twin cylinder engine, power-valves of one sort or another, and an aluminum beam frame. But each manufacturer went their own way trying to maximize performance within those fairly narrow parameters. While development eventually led to the NSR, RGV, and TZR all using v-twins, there were a few experiments along the way, and today’s TZR250 3MA represents an interesting attempt to solve the packaging issues inherent in two-stroke design.

Obviously, two-stroke engines are very compact by nature: with no overhead-valves or cams, they’re short, simple, and very light. But while the exhaust expansion chambers required for a performance two-stroke may not weigh all that much, their bulging shape takes up valuable real estate in a motorcycle. The famous “gull arm” swingarms of the period were one solution to the problem and allowed the chambers to tuck in close to the centerline of the bike to maximize cornering clearance. But the 3MA version of the TZR250 went a different route by reversing the cylinders so that the carburetors were at the front, with the exhausts exiting directly out the rear of the bike instead of curving around the sides or underneath. The bulbous expansion chambers fitted neatly into the seat, with the exhaust exiting through the tail.

The design was eventually replaced by the v-twin 3XV version introduced in 1991 after just two years, so the experiment can be considered a bit of a failure. But there’s nothing inherently wrong with the idea, and this is one of my favorite bikes of the era, at least in terms of looks and the weird factor: it’s my deep and not-so-secret shame that I haven’t ridden one yet, but here’s hoping that the stars will align and I’ll be able to find a decent California-titled example when the time is right. Scouting around the message boards, it seems that the bike’s reputation for poor reliability is exaggerated but, as these were not often seen anywhere outside of Japan, parts availability will prove difficult.

From the original eBay listing:  1989 Yamaha TZR250 3MA for Sale

The parallel twin reverse cylinder version. The bike is imported from Japan. Not registered yet in the U.S. This bike is sold without title. (NO TITLE) Start engine. Original Cowl. New Aftermarket Front fork innre tubes. Dragging brakes. Need to change tires (flat tire) and a battery. Some scratches and rust, so look carefully all pictures and video. This motorcycle is 28 years ago. Sold as is.

11271km (7003mile) LOW MILE. Sold as is with NO warranty NO refunds NO return. Buyer responsible for vehicle pick-up or shipping to your location. (ITEM AT CARSON NOW)

There’s also a helpful clip of the bike starting, running, and revving. The seller’s English is a bit limited, but it looks like the bike runs from the video and just needs a little TLC: a brake rebuild, new tires, and some minor cosmetic issues. Normally nothing you’d find shocking in a 28 year old motorcycle, but make sure you’re prepared to troll eBay and use Google Translate to track down parts to keep this running. It’s certainly not pristine and it’s not the cleanest example we’ve featured on this site, but if the price is right, it won’t take all that much to get this one on the road. Obviously, the usual titling issues apply, so I doubt this bike will remain in Southern California.

Restored Replica: 1984 Yamaha RZ350 for Sale

Tad Diemer 2

If you live here in the US and have a hankering for a two-stroke sportbike the choices, assuming you don’t want to monkey about with a grey-market import, are few and far between. 70’s two-strokes were relatively light and nimble, but still limited by the suspension and frame technology of the time, and by the mid-1980s, they’d been legislated out of existence, leaving this Yamaha RZ350 to make a final stand against the inexorable tide of four-stroke motorcycles. With blacked-out engine and frame, that striking black and yellow “bumblebee” paint, bikini fairing, and the “Kenny Roberts” signature, the RZ350 represents the very last of the old guard before “sportbikes” were codified into the narrow, very focused form we see in today’s motorcycles.

Produced for a very short period between 1984 and 1985, the RZ350 was a follow up to Yamaha’s RD bikes. It was powered by a 347cc two-stroke parallel-twin that added liquid-cooling to the successful formula, along with the “Yamaha Power Valve System” or “YPVS.” Powerband is typically two-stroke-y, even with the benefit of the YPVS power-valve, but the additional displacement helps some, compared to the all-or-nothing 250s. Weighing in at just 370 pounds or so with gas in the tank, it will still shake a leg on spirited backroad rides and can surprise modern machines, although tire choices for the skinny 18″ wheels will limit ultimate grip…

The seller claims that the bike has been restored from top to bottom, including a full engine rebuild, and it also includes a full-fairing that appears to have been a popular period accessory, considering the number of RZ350s fitted with them that come up for sale.

From the original eBay listing: 1984 Yamaha RZ350 Kenny Roberts Replica for Sale

Here is a beautiful restored 1984 RZ350 Kenny Roberts. The numbers are matching with a clear title in my name. This bike has a low production number of 223.  I have owned this bike for 6 years and have hardly rode it. It sat getting looks more than riding so its time to turn it loose. This bike has been completely restored. The engine has been professionally rebuilt from top to bottom. It runs and rides beautiful. There is less than 500 miles on this bike since it has been redone. As you can see it has a full fairing kit. The engine is stock with DG pipes and mild carb jetting. This bike is a real head turner where ever I have taken it. Probably the nicest RZ350 you will come across. Take a look at the pictures.

Bidding is very active on this one, and up to just over $7,000 with about 24 hours left on the auction. It’s certainly possible to find an RZ350 for less but, unless you stumble across some pristine, low-mileage museum-piece that will probably need a full restoration if you plan to ride it regularly, you’re unlikely to find one nicer. Well-reviewed when new and very popular now, the RZ350 neatly straddles the modern and classic eras, with clearly vintage sportbike style, light weight, and a liquid-cooled two-stroke punch. If you’re looking for US-legal two-stroke performance, this is just about the only game in town, and this example looks to be one of the nicest around.

Mark 1 – 1995 Aprilia RS250 Loris Reggiani Replica #275 of 500

Donn 8

The fact that it’s offered by a SoCal preparation shop specializing in Suzuki might be a reminder that the Aprilia RS250 used the 249cc two-stroke twin from the RGV250.  As enhanced by Aprilia’s intake, top end, and exhaust, the RS250 had power that put 4-strokes with triple the displacement to shame.   This first-year race replica has low miles, excellent cosmetics except for one faux pas, and a newly rebuilt engine.

1995 Aprilia RS250 Loris Reggiani Replica #275 for sale on eBay

Commemorating Aprilia veteran Loris Reggiani but capitalizing on Max Biaggi’s string of MotoGP championships, the RS250 brought GP technology to the showroom floor with the sculpted aluminum-magnesium alloy frame and swingarm, and carbon fiber seat subframe.  Bigger-bike Marzocchi suspension and Brembo brakes alert you to the possible speeds.  The full fairing is sleek and completed by details like factory billet rearsets.

 

Another victim of too many bikes / too little time, this RS250 has under 6,000 miles and looks great except for the right seat fairing, which might be remedied with a decal kit.  Not sure it’s the best thing on a low mile machine, but the fresh engine rebuild will require break-in and tuning, as the owner states in the eBay auction:

But probably the BEST THING about this bike is that it just had a full rebuild – crank, carbs rebuilt, pistons (rgv) new seal kit. Easy said and done over the internet  but i have photo’s to prove.
The bike is supplied with full jollymoto pipes, but oem ones are included (seat,rear passenger brackets )
Owners books (both keys) and original loris poster with sales advertisement’s
Bike does start but will need to be run in and maybe slightly tuned once its run in.

 

The small print for the RS250 included a powerband that doesn’t begin until 8,000 rpm, so there might be a learning curve there.  Ready to ride at 350 lbs., handling is sharp and the brakes are world-class.  Aprilia’s meticulous fabrication make the RS250, especially in the race replica, an exciting find…
