Pre-Tobacco Lawsuit: 1992 Honda NSR250 SP Rothmans

There’s something nicely poetic about a cigarette company springing for the racing efforts of some of the smokiest, dirtiest little rippers to ever grace the grand prix stage. It hearkens back to the devil-may-care days before airbag suits or adequate runoff, and celebrates a certain cavalierness that precious few subscribe to anymore. This 1992 Honda NSR250SP Rothmans will take you back to a time when even street riding required a level of focus that comes with the knowledge that the nerves between your brain and your hands are all there is to save you.

1992 Honda NSR250SP for sale on eBay

When unrestricted, these bikes made nearly 60 horsepower in a knife’s edge powerband and were known for their trim waistlines and extremely agile handling. As an SP model, this one got even lighter magnesium Marvic wheels, a dry clutch and fully-adjustable suspension. There is a lot of edge to this knife, and you have to have a very clear idea of what you’re doing to get the most out of it.

This example is a pure rider’s item. The seller says it wears aftermarket bodywork, which will be a ding for anyone who wants to tuck it into a garage and wait for the auction value to balloon. Those weird, non-stock Playstation stickers have to go, too. But, here is the good part: The bike was last owned by a mechanic and NSR freak, who, according to the seller rebuilt the engine and transmission bottom to top. It also wears recent and thoroughly modern rubber. It’s ready for the springtime riding season.

From the eBay listing:

Up for auction is a genuine 1992 Honda NSR250R SP (sport production ) Rothmans with a clear California title. I purchased the bike two years ago from a local motorcycle tech and NRS guru who has been working on and enjoying these bikes for many years. This NSR was completely rebuilt by him in his shop just prior to me purchasing it. Every part on the bike was inspected, rebuilt or replaced. The engine and 6 speed cassette transmission were redone using a brand new crank shaft, rods, pistons, and bearings. All plastic panels have been replaced with new. Other parts were repainted or polished as necessary. The original white MAGTEK magnesium wheels look great with newer Michelin pilot power tires. Mileage shown on odometer is not accurate. The original odometer has been replaced with a properly functioning used speedometer/odometer. The bike is all stock except for levers and stainless braided break lines and has also been de-restricted. This NSR performs as it should and is an absolute blast to ride. Unfortunately I am not able to ride it much and have only put about 1500 miles since its complete rebuild. I am a bit reluctant to sell this bike knowing that it will be very unlikely that I could find another one titled in my state. California has banned all future registration of 11 digit VIN numbers. Certainly this also means the value will continue to rise since the existing pool of California titled NSRs will never increase. I have done my best to describe the bike. Please ask any and all questions before bidding. Bike is available for viewing before auction end. I can assist buyer with arranging shipping. Buyer will be responsible for any shipping costs.

Winter Blues: 1984 Yamaha RZ350

As many parts of the United States are deep in the throes of falling frozen water, riding is an activity that must wait for warmer weather and more favorable road conditions. There are locales, however, where riding can commence year ’round. The southern states on both coasts serve as a great example. And it is from one of those states where we find this immaculate 1984 Yamaha RZ350, ready to ride. If you are snowed in and looking for that winter project that might require TLC and lots of mechanical know-how, stop reading now. This particular bike looks to need nothing but high RPMs and silly grins. If that is your idea of a winter project, read on!

The RZ350 is well known as the last of the factory 50-state street legal two strokes. Known as the RD350LC in other geographies, the RZ was the continued evolution of the parallel twin RD lineup, but with a healthy dose of modern tech thrown in. Sure the chassis was mild steel and not aluminum, but that did not stop the RZ from sharp handling. Brakes were triple disks, rear suspension was of the new-fangled single shock design, the venerable twin was now liquid cooled for tighter tolerances and greater power, there was a computer controlled bridge attached to the exhaust port to spread the notoriously peaky powerband around some, and the exhaust pipes were fitted with catalytic converters to help the dirty two-stroke meet EPA emissions. In most ways it was a toned down version of itself, but the beast within was woken up easily with a few common two-stroke tricks. The party only lasted two years, but it remains a very memorable party indeed.

From the seller:
1984 YAMAHA RZ350. Bike has less than 500 miles on a total renovation. Stripped to frame, wheels, bodywork all painted. Original exhausts go with the bike. Brand new Original CDI Spare also goes with the bike. The bike does not need anything. I never ride it anymore to many other things going on. Clear title, the bike is in ORMOND BEACH FL.

I have a reasonable reserve for this bike in this condition. Please do not message with silly offers. The bike sits in my climate controlled building and is available to view anytime. Everything works as you would expect. The gas cap area has been treated with an epoxy to resist any gas overflow from affecting the paint in the silly recess around the gas cap. (yes I have overfilled it) Not much more I can say. If you are looking for an RZ that requires nothing but a rider then you know what you are looking at.

There is a fair bit of interest in this particular RZ, and the eBay auction has a good number of followers. Bidding history shows the relatively quick escalation from $2k to the current bid of $7,400 – but we can be pretty certain it won’t stop there. The seller indicated that there was a reasonable reserve set for the bike, and that is clearly the case; the reserve has already been met. Whatever happens from this point forward, this bike is going home with somebody. Check it out here and let us know if this isn’t the cleanest RZ you have seen in quite some time. It has some aftermarket expansion chambers (great for waking up the beast) and the seller will even throw in the original pipes with the deal – which is great for someone looking for an original collector. The RZ is a constantly sought-after machine, and we anticipate prices to continue to rise. If you are in the market, best jump in while prices remain somewhat sane. Good Luck!!

Featured Listing: 2009 Aprilia RS125 Jorge Lorenzo Edition

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
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.

What Could Be – 1986 Honda NS400R

With most riders expecting the best part of 200 hp per liter, later two-strokes of middling displacement are often treated like caged animals. This Honda V-3 doesn’t appear to have been babied, but does boast current California registration.

1986 Honda NS400R for sale on eBay

Honda acknowledged that the 500cc GP formula was not going to be won with the four stroke NR500, and returned to the podium with the NS500.  Wishing to capitalize on their success within Japanese regulations, they presented a 387cc race lookalike, which was brought stateside in a plain gray wrapper.  The surprisingly symmetrical triple had two forward cylinders and the third more vertical.  The bank of three 26mm Keihin carburetors are plumbed directly in from the top, with the outside exhausts riding underneath and the center taking a scenic underseat route to the license plate.  Even with Honda’s ATAC power valve, acceleration below 7,000 rpm is gradual, then a controlled explosion to the 9,500 rpm peak of 72 hp.

Thirty-plus years on, almost every bike will have some unknowable history.  This example has evidently received more attention on the mechanical side than to the out-front details that grab eyeballs.  Seems like doing about 10% of the required beautification would make a 90% improvement.  From the eBay auction:

Just serviced and ready to ride.  Has some cosmetic issues as can be seen in the pictures, but the previous owner installed a brand new engine which has less than 1,000 km or less than 600 miles on it, even though the odometer reads 26,296 km which is about 16,400 miles.  Odometer may change slightly as it is ridden occasionally to keep it in great running condition.  Starts easily and runs great, but needs new kill switch assembly.
Previous owner had installed a new engine, and we rode this bike a few times over the years, but with 60 bikes in the collection it did not get ridden very often. I had it completely serviced in August 2019 and new CDI units were installed (this bike uses two).  Just had the carbs cleaned last week so it is running fine.  The bike has a CA title and registration and I have it in hand.

The livery on this NS400R is similar to Honda’s GP works livery in the early 1980’s, when Freddie Spencer was quickly drafted from Honda’s AMA Superbike effort.  Spencer hit pay dirt in 1985, winning at Daytona as well as the 500cc and 250cc GP championships.  This NS400R has a lot of question marks – high mileage, engine change, and pictures that serve only to start a conversation.  But if some of those could be resolved, it might justify the owner’s reference to a high-dollar Mecum auction winner.

Pint-Sized Oddball Exotic: 1986 Cagiva Aletta Oro S2 for Sale

When you see “Oro” in a motorcycle name these days, it immediately conjures images of low-production, high-spec exotics like the MV Agusta F4 750 Serie Oro. This little smoker was really anything but “limited-production” or “high-spec,” and Aletta Oro translates to “golden wing.” Of course, it’s obvious that it has nothing in common with Honda’s famous luxury touring mount, other than it being a motorcycle. Instead, the Cagiva Aletta Oro S2 was intended as a classy, entry-level bike with limited performance and plenty of style.

As you’d expect from an entry-level European machine, the Aletta Oro was powered by a motocross-derived, liquid-cooled 125cc two-stroke, with automatic oil injection to keep the little motor happily smoking. A six-speed gearbox helped newbie riders keep the engine in the meat of it’s meager powerband and make the most of the claimed 23.6hp. Thanks to a 277lb claimed dry weight, the little Cagiva could keep pace with its contemporaries in a straight line and the bike was a nimble handler, although ultimately limited by the budget suspension components.

Styling is very, very 1980s with pearl white bodywork and a red frame. Fuel goes in the normal place at the top of the tank, but the right-side fairing features what looks like a fuel door that hides the radiator cap. The dash is pretty comprehensive, although not shown here, with an absolutely huge tachometer front-and-center, temp gauge, and a digital fuel gauge, as well as the usual speedometer and row of idiot lights.

From the original eBay listing: 1986 Cagiva Aletta Oro S2 for Sale

I purchased this bike off of original owner in about 2017 and installed a brand new Polini 162cc cylinder at my shop in New Hampshire. This is a stock bike otherwise originally 125cc 6 speed liquid cooled 2 stroke auto mix. Dash works and headlight/taillight work. Turn signals are cracked a little and have been repaired once (very poor design). I have personally taken this bike apart and ridden all over NYC this past summer and fall. Bike does a healthy 75+mph and shifts through all gears. Starts 1 kick and sounds very healthy. Can provide videos and additional photos upon request.

CLEAN STREET TITLE AND REGISTERED IN MY NAME. CURRENTLY BEING USED ON ROAD ONCE A MONTH OR SO.

Please keep in mind this is a very rare all original bike and there are almost none of these in the USA. this is not a showpiece but a running riding bike perfect for inner city domination or to hop on the highway for short trips here and there. 

I can also deliver up to 350 miles of NYC for Gas/tolls/fee discussed. Thanks.

The bidding is currently up to $2,000 with a couple days left on the auction. I highly doubt these will be worth much anytime soon, but you can’t beat a weird 80s Cagiva for novelty value. And, unlike a Motocompo or Monkey, it’s a thoroughly usable novelty, one that could make a great commuter or city bike, as the seller mentions. The biggest issue would likely be bodywork, although I’d expect you should be able to find plenty of used parts, if you’re willing to look online and trust shippers outside the US. This one isn’t pristine, but when will you have another opportunity to pick up something this rare for so little?

King Kenny’s steed: 1985 Yamaha RZ350

The Yamaha RZ350 lived a pretty short life on these shores, eventually leaving us in the face of EPA fleet emissions regulations and sales that paled in comparison to its bigger four-stroke stablemates. But, if you were serious about roadracing, or were a serious fan of the 500cc Grand Prix races of the time, the RZ was your mount. The little parallel twin leaves none of its inspirations to the imagination, wearing the signature of American 500cc ace Kenny Roberts front and center on its red, white and blue frame and bodywork.

1985 Yamaha RZ350 for sale on eBay

With just about 45 horsepower, none of which was available until about 6,000 RPM, the 375-pound RZ rewarded momentum and bravery over raw power and speed. Still, even with limited horsepower, the thing managed to click off a 13-second quarter mile at 100 mph in the hands of CycleWorld. That is musclecar shaming performance in a package that will turn with aplomb when you ask it to.

This 1985 Yamaha RZ350 has a few tasteful mods and has covered just under 12,000 miles in its 34 years. It is in very nice condition, with just a few scratches, dings and touch ups on the frame and body work.

From the eBay listing:

1985 Yamaha RZ350 Kenny Roberts

NO RESERVE

11,983 Miles
Fox Shock

Powder Coated wheels
New Fork seals and oil
Brakes completely gone through
New EBC rotors and yamaha pads

Hard to find Stock pipes
Tank is clean and rust free inside
Great condition ready to ride
Few minor scuffs as seen in photos
Touch up on frame

Buyer pays shipping (I can assist with shipping) Local pickup in Sarasota, FL area

With no reserve, this thing will sell come hell or high water. With the best part of a week to go in the auction, we’ll be curious to see what this pretty little smoker fetches.

1/2 Liter Superbike – 1987 Yamaha RZV500

While the roadgoing two-stroke era ended here in 1979, it continued for several more years around the globe, a few makers templating their Grand Prix bikes for the showroom.  This example looks under used and has a super-clean stock appearance.

1987 Yamaha RZV500 for sale on eBay

The RZV was destined only for Japan, and differed from the rest-of-world RZ500LC mainly in its alloy chassis.  The compact V4 is actually two upright twins which are geared directly to the clutch, and the lack of a central jackshaft left room for a smoothing counter-balancer.  Two pairs of 26mm Mikuni carburetors look to the sides, and expansion chambers leave from the front and rear of the V.  Forks are air-adjusted, have anti-dive and hold dual 267mm brakes and a 16-inch front wheel, while the 18-inch rear is mounted to an alloy monoshock.

The Seattle dealer showing this RZV500 has had a few other classic sportbikes on eBay ( and RSBFS ) along with a boatload of parts.  The RZV has just under 6,000 miles and looks excellent in several high-resolution photos.  Not sure exactly what to expect in the sticker department on a JDM machine, so expert readers will have to weigh in.  Comments from the eBay auction:

The body work is all original and is in very good condition. The paint work is in nice good condition with no major scratches anywhere, and wheels are in great shape with no major rock chips or corrosion. The frame does not have any corrosion and is nice and clean. The original exhaust is in nice condition with the exception of one dent on the right side muffler as can be seen in the pictures. But overall cosmetically this bike is in very nice condition.

The bike runs and rides perfect, and shifts smoothly through all gears. The carburetor was recently ultrasonically cleaned and adjusted, and a full service tune-up was performed which included new spark plugs, chain, brake pads, oil change, new tires, and all fluids flushed. All of the lighting, switches and electrical components work as they should.

With almost 200 hp per liter ( when de-restricted ), the RZV was too fast to live and production ended in 1988.  Several anachronisms flying in formation, it’s a two stroke, kick start, and weighs just over 400 lbs. dry.  Likewise, maybe you are more comfortable in your helmet and knee sliders than business casual, and would like to get in on the bidding.  It’s just eclipsed $13K but hasn’t yet met the reserve.

Chi Slamma Gamma – 1986 Suzuki RG500

Fully ten years after Barry Sheene won the GP world championship on his RG500, Suzuki had tamed the beast for the showroom.  Though the delay missed the window of opportunity in the U.S., many examples have been imported, and this looks like one of the finest.

1986 Suzuki RG500 Gamma for sale on eBay

Unthinkably complex in this day of 400cc singles, the RG was actually two 250cc twins geared to a common lay shaft, which was protected by a shock damper on the road machine.  The low-profile 28mm Mikuni carburettors and their air shared filter are wedged against the sides of the fairing, with disc induction valves underneath.  Suzuki’s Automatic Exhaust Control power valve system and expansion chambers made their way aft closer to the centerline.  Alloy chassis and cast frame connectors  are seemingly more modern than the earlier race bike, the seat fairing covering the upper exhausts and stretching all the way to the footpegs.

With just over 6,000 miles, this Chicago resident is even better looking than the odometer would suggest, with no evident runs, hits, or errors.  The owner says this in the eBay auction:

As you can see from the photos in the photo section as well as the body of the description, the machine has had absolutely no restoration performed to any part of it.  The condition is exactly what it looks like in the photos.  I looked at a quite a few of these bikes before I finally bought this one, and I’ve never seen a better original one before or since.

The paint on all of the fairings, tail section and tank is original, and have never had any type of paintwork or touchup.  The fairings have never had any type of cracks or damage.  The bike has never been in any type of accident or been dropped at any time.

The RG500 runs and rides the way you expect a machine with this type of mileage to run.  All of the mechanical components have been checked over to ensure they work properly including the clutch and brakes.  The fuel delivery system was also completely gone through this season and functions perfectly. 

Suzuki began the square four saga with two 125’s making 250cc, and offered a 400cc variant alongside the 500 in appropriate markets.  But the RG500 was the race winner, and the great powertrain was in a 340 lbs. ( dry ) package, a power-to-weight ratio that was years ahead of its time.  Bidding is quite active but hasn’t met the reserve, and we’ll be keeping an eye on this one.
