Featured Listing: 2005 Aprilia RS50

In these trying times there is tremendous fear as to what might be to come. Worried about raiding your retirement account to purchase that perfect collectible specimen of a RC30 / OW01 / Mh900e that you are not likely to ride? Then how about setting your sights a little lower – as in lower seat height, lower capacity, lower investment risk and lower entry point. The only things that are not reduced with this plan are the cool factor and the fun. Today’s 2005 Aprilia RS50 is the perfect example of this “less is more” philosophy. This is an awesome little bike that allows you to channel your inner Max Biaggi and ride at 10 tenths without risking everything. It looks great and would make a fantastic addition to your man cave or garage. But please don’t miss out on riding – there is absolutely *nothing* like riding a slow bike fast. Those who have tried it would tell you about it, but they can’t stop smiling long enough to talk.

Featured Listing: 2005 Aprilia RS50

The RS50 is not your average little moped. For those raised on MB5s, AR50s and YSR50s (you know who you are), this Italian wonder is a mini GP bike on steroids. Under the full MotoGP fairing enclosing an aluminum, liquid cooled, single cylinder Motori-Minarelli engine (later units were built by Derbi), the RS offers some pretty advanced technology including a full aluminum frame, 17 inch cast wheels with a large 300mm front disk, and 40mm forks. Dry weight slips by under 200 lbs. Power – if you have to ask – hovers around 10-ish provided the tach is pointed at the 1:00 or 2:00 o’clock position. And that is where the fun lies with riding a bike such as this; nothing teaches you corner entry speed, conservation of motion, gearbox management, tachometer awareness and – perhaps most importantly – how to tuck in tight.

From the seller:
2005 RS50 with 1412 miles. Bike is all stock except for Leo Vince V6 pipe. Great condition overall except for a few minor scuffs here and there. Starts, runs, everything works as it should. New Mitas tires. New Antigravity LiON Battery. Comes with 2 keys, 1 liter of injection oil and a new Naraku 70cc BBK never fitted. Bike ready to go and is located in Cary NC

Clean & clear NC title in my name. $1900 or best offer.

The US has never truly embraced the small-bore racing set. We don’t have license restrictions like they do in Asia and Europe. American riders tend to cut their teeth on bigger bikes, and as a result they see small motorcycles as entry level. But if you can work the sliver of a power band and minimize the limitations of the format, you can scare yourself silly while having the absolute time of your life. Anybody with access to a karting track knows they need one of these. And regardless of your age/weight/displacement preference, this is something that will make you a better rider. There is simply so little room for error that by simply tooling around on this type of bike you become more focused and aware. You want to improve your skills? The line forms right here.

And the best part of today’s offering is how accessible it is for nearly everybody. I don’t know how to say it gently, so I’ll throw it out there: this bike is priced to sell. The seller is a fan of the site, and is looking to change out his current stable a bit. So if you want to become a better rider, learn skills that directly transfer to a bigger bike, feel like Rossi without ever breaking the speed limit, or simply want an uber cool piece of artwork, reach out to Roy. He is one of us and gets it. There is not a lot of power here, but this one will move quickly. Check it out, and Good Luck!!

Formation Flight – 1985 Yamaha RZ500 with 4,600 miles !

With a pair of 250cc engines driving a common output shaft providing two power strokes on every revolution, Yamaha’s RZ500 pushed nearly 200 hp per liter, even in street trim.  This sharp Michigan example has been in storage but was recently freshened up for riding season.

1985 Yamaha RZ500 for sale on eBay

The RZ’s engine is almost a cube, with four 26mm Mikuni carburetors looking out to the side-mounted airboxes from the valley of the 50-degree V.  Individual expansion chambers wend their way back, with the upper cylinders’ pipes tucked into the seat fairing.  88 hp was available at a wailing 9,500 rpm, with the torque band was stretched by the YPVS power valve system.  The chassis was steel tubing and the forks were right-side-up, though the monoshock was underneath the engine to make room for the exhausts.

With just over 4,600 miles, this RZ had to be in storage before the present owner.  Just some stress cracking on the chin scoop is apparent, with none of the usual garage rash and corrosion.  The seller waited seven years to re-commission it for the road, and has the following comments in the eBay auction:

New Battery
New Tires
New Chain
New Wheel Bearings
New Tapered steering head bearings
Changed transmission Oil
Cleaned float bowls on carbs
New Shut off valve for fuel
New front Brake Pads
Amsoil Dominator Synthetic injector oil
New fork seals, Race tech Springs, Gold valves, Modified damper rods (per Race Tech) 20 wt oil
With modifying damper rods the Anti Dive units are inactive (left them for stock appearance)
 
This is a very nice mostly all Original RZ, Starts first kick most every time hot or cold, shifts and clutches fine, pulls all the way to redline.
 
All lights work, horn, blinkers, brake light, gauge lights

The RZ500 waited more than 10 years to hit the streets after the YZR500 race machine’s 1973 introduction, but by then the U.S. and a good part of Europe had declared two-strokes unwelcome.  So every RZ500 seen will be a gray market import with limited history, and a KMH speedo with MPH sub-titles.  This one’s about as nice as they come without claims of a collection or museum, and the auction’s at $11K with five days to run.  With recent sales in the low $20’s, a lot of us will just be watching, at least to see where the reserve is set.

Featured Listing: 1996 Aprilia RS250 Mk. 1

This 1996 Aprilia RS250 Mk. 1 is an RSBFS alum that has come back for a master’s degree looking much sharper than it did the last time it crossed our desks. For one thing, the year has been corrected, the VIN shows it’s a 1996, not a ’97 as we said before. Oh yeah, and the seller has spent more than $4,000 making it even sharper than it was last time we saw it.

Modifications include a set of BST carbon fiber wheels and a 2015 Suzuki GSXR front end, which means radial brakes and much more modern fork internals than this thing originally relied on. It also comes with almost $3,000 worth of spares, including Lance Gamma engine cores, new fork tubes, the original Aprilia wheels and front end, a battery tender, the original KPH speedometer and on and on. It is, in a word, sorted.

The 250cc Suzuki-supplied two stroke mill was refreshed at around 12,000 miles by the previous owner, and the seller has added just 400 to that total since he purchased it in August of 2018. With 72 horsepower available at 12,000 rpm, Suzuki suspension and feathery carbon wheels, this Aprilia RS250 is an expression of what Aprilia would have done with an unrestricted budget and technology.

From the seller:

Over $4k in updates since purchase:
2015 GSXR 600/750 front end
Tubes have some rash – 2 brand new black tubes (with spares)
New steering head bearings and seals
Galfer wave rotors and titanium hardware
Unpainted GSXR fender
BST Carbon Fiber Wheels
3.5×17 for GSXR with ceramic bearings
5.0×17 for RS 250 with ceramic bearings
Metzler M7 tires 120/70 & 160/60

Rode less than 200 miles since 8/2018 – less than 15 with BSTs and no speedo. Garaged entire time and looks like it did when I bought it in 2018.

Over $3k in spares:
Battery Tender
Lance Gamma RG 500 core and spare RG400 case
Pit Bull front and rear stands
(2) 51131-14J00 Black Outer Fork Tubes
MK2 ft end
Original MK1 front end and both wheels
Original passenger seat and passenger pegs
Original KPH speedometer
Original clear windshield
A *new* set of factory style stickers
Parts and repair manuals
All receipts from last and current owners
Original German government documentation

Seller Steve is asking $13,500 for this sorted Italian icon. That number buys you a lot of bike on any market, but with the list of mods and spares this one has, it could be the perfect escape from COVID-19. The seller can be reached at: slow_five0@yahoo.com.

Featured Listing: 2009 Aprilia RS125 Jorge Lorenzo Edition

Update 4.14.2020: Seller is motivated and has lowered the price to $5,000. Contact Matt: matthewsumma@hotmail.com or cell/text 816-914-0516.

Before the three MotoGP world titles made him synonymous with factory Yamaha, Jorge Lorenzo made a damn solid case that he was the next GOAT on 125cc and 250cc two-stroke Derbis and Aprilias in the big show’s feeder series. After three seasons on Derbis in 125, Lorenzo made the leap to 250s with Honda in 2005.

But in 2006, he moved from Honda to Aprilia and everything changed. He put the series on his back and ran to the next two world titles aboard the Fortuna-liveried Italian machines. This 2009 Aprilia RS125 pays tribute to those machines and those championships in the “Spain’s No. 1” livery that Fortuna used in countries that forbade tobacco sponsorship.

With just 28 horsepower, you’ll never challenge a Lorenzo lap record on one of these things, but with less than 300 pounds to push around, there’s plenty of fun to be had, especially when the road gets skinny and twisty. With just 10 miles on the dial, it’s safe to say this one hasn’t been fully enjoyed yet. It’s a US version, which means its lights are inoperable and it hasn’t got mirrors. Thanks to the EPA, this thing was never going to be legal on these shores. But as a short-track blaster or a pure collector’s item, its pedigree is hard to argue.

From the seller:

For sale is a 2009 Aprilia RS125 Jorge Lorenzo Special Edition. This bike is like new, show room quality with only 10 original miles. This is a motorcycle collectors dream! Not only are they super rare in general, but you won’t find one in this condition with this low of miles unless it’s still in the crate.

Price: $6,000 $5,000
Contact Matt: matthewsumma@hotmail.com or cell/text 816-914-0516.

You can park this little ripper in your shop for $6,000, which is less than a dime-a-dozen Suzuki DR-Z.

Pint-Sized ‘Prilia: 2002 Aprilia RS50 for Sale

A rare sight here in the US, the Aprilia RS50 was pretty common overseas, where strict licensing laws made these a must-have for aspiring sportbike pilots who didn’t yet qualify for the overwhelming power of a 600 or even 400cc machine… Of course there are plenty of good reasons to ride an RS50, even if you’ve long-since graduated to a larger machine. Weight is the enemy of performance and, while the little Aprilia may not produce much power, at around 200lbs dry it also doesn’t have much in the way of weight.

The tiny displacement meant that the RS50 was classified as a moped, although it really was more a small motorcycle, with 17″ wheels and a six-speed gearbox. The overall package was more sportbike than scooter as well, with a twin-spar aluminum beam frame, a monoshock rear, and disc brakes at the front and back. It was sold here in the USA from 1999-2003, although it continued to be built much later in other markets.

As usual, Aprilia didn’t build the engine in-house, so the RS50 was powered by a liquid-cooled, two-stroke Minarelli AM6 engine displacing 49.7cc. All that snarling power could push the lightweight machine to 55mph, and this bike’s 75cc big bore kit should pretty much double the engine’s output… Keep in mind, these were raced in Europe, so plenty of tuning and suspension upgrades exist.

I haven’t shopped for RS50 parts, but these were popular outside the US, so it shouldn’t be too hard to track down a replacement fuel cell, or perhaps a professional repair might be possible?

From the original eBay listing: 2002 Aprilia RS50 for Sale

This owner of the bike modified and upgraded this Aprilia with the purpose of making it the best RS50 around. It has a 75cc top end with a moly coated piston. A 24mm flatslide Mikuni feeds water cooled cylinder and a silver ceramic coated Arrow exhaust has been added to round off all the performance enhancements.

It has AF1 triples and a custom backed instrument cluster. In addition to being a unique head turning motorcycle on it’s own this model sports the nearly endangered Black Lion body and logos. You’ll likely never see another one like it in the wild.
The bad: this is literally a “ran when parked” situation. The fuel cell cracked next to the the tap screws. It was fixed with a fuel tank epoxy and patch but that eventually started to leak. Ultimately it will need another tank. In mid-January the back tags for the registration in California came to $740. Fortunately we can arrange shipping to the other contiguous 47 states (or factor that into your bidding). I have a very reasonable and trusted shipper from whom I can get a quote and time. Just contact us before bidding to confirm the price and eta.
This is definitely a head turning joy to ride. When people hear it coming they don’t expect to see this pull up. It was genuinely built by the owner with the long term purpose of being reliable, ride-able and fun.  
Well, the leaking fuel cell will obviously need some work, but the price does reflect that: just $1,750 for this little hot-rod two-stroke. Miles are pretty low, and the bike does have a few nice extras, like that big-bore motor, top triple, and the Arrow exhaust. All together, the package should be good for more than 9hp at the rear wheel and 75mph with favorable winds, a huge leap from stock power. If you’re looking for a cool, low-cost project bike that shouldn’t take too much to get rolling, assuming you live outside California, and can dodge those back registration fees…

Pedi-greed is Good – 1996 Aprilia RS250 Reggiani Replica

Pictured in last fall’s fading foliage, this Aprilia stands out in the factory’s racing red, blue, and silver.   When riding season gets here, the list of recent services makes sure it’ll be ready.

1996 Aprilia RS250 for sale on eBay

Though Aprilia couldn’t waste time making their 249cc engine from their racing RSV250 meet DMV’s requests, they could design exhaust and intake systems for Suzuki’s RGV-250 engine and increasing the output to 73 hp.  Displacement was limited, but the thin-wall alloy chassis was overbuilt, as well as a work of manufacturing art.  Adjustable Showa suspension could have been for a mid-size machine with a similar banana swing arm.  Four-piston Brembo calipers were planning on hauling the little Aprilia down from triple-digit speeds.  A little bulbous in street bike paint, the race-rep livery works magic on the single-seater.

Seeming to have been owned only since this RSBFS – post – the owner has kept it nice and improved a few things.  Notes from the eBay auction:

The bikes has a clear title and the only additions to it are an Ohlins steering damper, smoked windscreen, and a battery tender lead.  The following services have been done to the bike:

  • New Battery
  • New Spark Plugs
  • New black stainless steel brake lines front and rear
  • New brake pads
  • New air cleaner
  • New Pro-Grips
  • New Chain Guide
  • All fluids replaced and topped off
  • Carbs rebuilt
  • New tires
  • New chain
I also have a box of take-off parts that are included in the sale that are worth approx. $1000-1500.
  • RH switch gear
  • Grips
  • Flywheel
  • Voltage Regulator
  • Clutch Assembly
  • CDI box
  • Oil Pump
  • Rear brake master Cylinder (NEW)  
  • Also including a factory service manual

Make Offer button is lit so forgive the ask and undo the CapsLock button before commenting.  Still in the 30’s every night where this RS250 lives, but real spring is just around the corner.  Reggiani was an able Aprilia pilot, never achieved the championship but gave the team their first GP win in 1987.  The red/blue paint becomes the diminutive RS, and its capabilities would surprise many riders on bigger machines.

Bantamweight Racer: 1981 Honda RS125RW for Sale

Today’s Honda RS125RW might be a bit obscure for most of our readers, and is certainly older than the bikes we usually feature here, but a genuine Honda Grand Prix machine is certainly worth a look whenever one comes up for sale! This one has plenty of patina, period stickers, and an apparently rare dry clutch for less weight and extra noise!

Honda’s Grand Prix racing motorcycles were based around four-stroke engines until the two-stroke MT125 was introduced in the 1970s. The MT125 was replaced in 1980 by the RS125RW seen here, and that machine soldiered on until it was replaced in 1987. The significantly updated RS125 introduced in 1987 was eventually developed into the dominant machine more familiar to most of our readers.

Powered by a motocross engine borrowed from the RC125M, the RS125R’s liquid-cooled, reed-valve engine made 30hp from 124.9cc with a bore and stroke of 56 x 50.6mm. The frame was a twin shock, steel duplex design, had disc brakes at both ends, and weighed in at 170lbs dry. It wasn’t considered cutting edge when new, but it was reasonably successful in competition and Honda continued to develop the bike and its successors as an over the counter racing machine available to younger racers honing their skills.

From the original eBay listing: 1981 Honda RS125RW for Sale

1981 Honda RS125R-W located at our shop in Santa Ana, California. The pictures in this auction were taken at our shop in Japan. This RS125R-W is in very good condition for its age. Engine has a super rare dry clutch. The previous owner said he rebuilt the engine before it was put away many years ago. RS125R-W are very hard to find now. This bike is the best we have had for many years now. And the only one we have had with a dry clutch. Bike will come with a new windscreen not mounted to the bike. There are no spares with this bike. Bike is sold as is, no returns. Look at the pictures carefully and ask questions before you bid. Sorry, no Paypal on this item. Again, bike is sold with a bill of sale, no title. Bike comes with what you see in the pictures in this auction.

The starting bid is $6,995 with a few days left on the auction and no bids as yet. This one is obviously a bit of a gamble, since parts to keep one running will be difficult to source. The engine is said to have been rebuilt, but I’d be prepared for the worst if it was my money. Experts might have a line on what they might need to actually ride it, and this bit of Honda racing history would obviously make an awesome display piece for your living room or the lobby of a business, if you just want to show it off in all its period patina.

Featured Listings: Pair of 1994 Suzuki RGV250R VJ22 Lucky Strikes

Update 3.12.2020: The VJ22 with Arrow exhaust has sold. Gary’s FINAL gray market bike from his outstanding collection is now on eBay with No Reserve. This last Lucky Strike is a fitting way to close. Links updated – act quickly before it’s gone!

It shouldn’t need to be explained how deliciously apt the Lucky Strike livery was for the Suzuki RGV250R, a competition terrorizing, rule-bending hooligan of a lightweight sportbike that smoked like a chimney and is as un-PC as grandad at an open bar. These little Suzukis are the stuff of my mid-1990s bedroom wall, and our friend Gary in Utah has not one, but two of the little curs. For the price of a new Hyundai, you can have a brace of the finest oil-burning track machines Japan ever spat out.

Built around a 90-degree v-twin that was good for around 70 horsepower uncorked, the 1994 Suzuki RGV250R VJ22 made its name shirking tiered licensing rules and treating roadracers to quick, precise handling that you just couldn’t match on a bike with loads of horsepower and a big waistline. On these bikes, the heritage as a racetrack terror is carried to the bodywork, where the big Lucky Strike logos ape Kevin Schwantz’s 500cc GP World Championship machine. We could think of few people to better personify the RGV250R than the waifish, aggressive Texan.

The pair here, in true Gary fashion, are immaculate, though one is ever so slightly nicer than the other. The bike with the Arrow pipes and black passenger seat is a little straighter, and has newly powdercoated wheels wearing a new set of Dunlop Sportmaxes. It comes with a standard exhaust should you want to take it back to stock. The bike with stock cans and a red seat needs a powdercoat and comes with an aftermarket exhaust if the stocker is too tame.

As with anything Gary touches, they have recently had all mechanical systems checked and refreshed.

From the seller:

Both bikes are 1994 models. Vin numbers confirmed genuine lucky strike models. L.S. With Arrow exhaust system has newly powder coated wheels and new Dunlop sport max tires. New drive chain. All fairings are 100% genuine OEM Suzuki factory. Genuine OEM new black passenger seat. Bike comes with OEM stock exhaust system. Customized with gold anodized bar ends. 7,427 kilometers.

L.S. with stock pipes and red passenger seat has 4,903 kilometers. Aftermarket exhaust comes with the bike. All stock condition. All fairings and components are 100% genuine OEM factory Suzuki. Bike could use the wheels powder coated but still looks very nice. Tiny ding in the front right side gas tank. Both bikes are minty low mileage examples. Both come with Utah state titles and are titled as street bikes for road use.

Both L.S.’s run like new. Both have had carb cleans….They both have new engine fluids, new brake fluid and both have had fork seals replaced and new fork fluid. Electrical components are 100% operational as new.

Askng $11,900 each.

Maybe you and a friend are in search of the next track day thrill, or maybe you want a buddy bike for weekend canyon carving, or, hell, maybe you just want one to ride and one to polish. Whatever floats your boat, these things have you covered.
