Three for the Road – 1985 Honda NS400R

In the spate of GP racer replicas that littered the 1980s, perhaps none are as perplexing as the Honda NS400R. Patterned after the NS500 that Freddie Spencer rode into the history books (with a nod to the RS500 privateer machines), the NS400R shared the GP bike’s odd 3-cylinder arrangement. And while the NS400R was the biggest two stroke street bike in the Honda arsenal, it was seriously outgunned by both the Yamaha RZ/RZV500 and Suzuki RG500 Gamma. Still, the Honda brought some innovate touches to the party and should be considered for anyone interested in a GP replica from the era of the smokers.

1985 Honda NS400R for sale on eBay

Like the big Yamaha, the Honda NS400R arranges the cylinders in a 90 degree vee formation. But in the Honda’s case, there are two cylinders laying flat in the front of the motor, and the single rear cylinder sticks nearly straight up. This allowed Honda to centralize the mass of weight lower, and closer to the ideal location for weight balance. The lack of a 4th cylinder simplified packaging of the individual expansion chambers and triple flat slide carbs. This unusual powerplant was nestled into a boxed-section aluminum frame which optimized geometry for the GP-inspired 16″ front wheel. Dry weight was reported to be a relatively svelte 360-ish pounds, and with 71 HP extracted from the screaming three cylinders the Honda was perhaps the easiest of the big two strokes to handle.

From the seller:
1985 Honda NS400R in an original unrestored condition as it came from Japan starts and shift like it is a 2 strokes beast. All original including the windscreen which is a very hard to find an NS400R with original windscreen. The motorcycle still wears its original paint. It was not been dismantled nor been altered or tinkered with. I bought it from a motorcycle dealer in England who imported it from Japan. It was not cheap and easy to get it here and register it. I replaced the battery (Yuasa), chain (DID), the front tire (Bridgestone Battlax), grips and the handlebar weight with nos ones. It comes with a clear title Japanese and brochure. The bike is registered with clear Texas title in Hand and in my name. Checks/money orders have to clear before I release the motorcycle. Deposit is non refundable.

Area that needs attention:

Front upper and lower fairing
RPM needle sticks sometimes
Broken Left peg

Fun little Honda quirks abound on the NS400R. Front forks are air adjustable with anti-dive assist. Out back there is an aluminum swingarm acting on a Pro-link single shock with preload adjustment. The aerodynamic fairing covers the majority of the bike, and includes touches such as aero fairings on the forks AND the kickstand. Pretty cool!

The Honda NS400R is a real gem from back when the Japanese were trying all sorts of engine combinations to find success at both the showroom and the racetrack. Today these are hard to find in decent condition, and they always command a pretty steep price. Today’s bike is not perfect – as highlighted by the seller in pictures and text, but it is certainly presentable. There are some scuffs here and there which is to be expected from a used bike of this age. The solo-look seat cowl seems to be missing, and (to me) the front fender looks slightly different than the brochures for the red/white/blue models – but does look consistent to the Rothmans livery models. This might be due to variations in components for different geographies; experts on the model are welcome to chime in. The asking price for this one is, well, steep: $17,500 in Buy It Now format. You can check out all of the details here, and Good Luck!!

Featured Listing – Historic 1999 Aprilia RS250 Challenge Cup with just 664 miles!

Update 10.6.2022: This bike has SOLD! From the seller, “I have sold the bike. Allow me to express my appreciation to YOU and RSBFS for your wonderful service and building such a large network of like-minded viewers.” Contact us for your own Featured Listing! -dc

Today RSBFS reader John M. brings us a fantastic bit of racing history. The Aprilia RS250 Challenge offered a true one make race series celebrating what was essentially the last of the two strokes. And for the occasion, Aprilia ran off a batch of Cup bikes that were devoid of pesky D.O.T. goodies such as 17 digit VIN numbers, lighting, etc. These were bikes that were only intended for track duty. And this particular one raced… and won. The winning rider for the 1999 US championship series – on this very bike – was John Hopkins. If you are newer to racing, you might recognize John Hopkins’ association with the American Racing entry in the Moto2 world championship (supporting American riders such as Joe Roberts and Cameron Beaubier as a coach). If you have a bit more history with racing, you will know him as a WSBK Superbike competitor, a British Superbike participant, an AMA Superbike rider and a genuine MotoGP racer, having tasted both the 500cc two stroke era, as well as the transition to four strokes on both 990cc and 800cc machines. Today’s Featured Listing is the RS250 that John rode to the 1999 Aprilia Cup championship. This bike was also a winner with Aaron Clark at the help in the 2000 Daytona Race of Champions. And if that is not enough historical significance, the bike was built, fielded and maintained – and ultimately sold – by the legendary Team Hammer crew.

Historic 1999 Aprilia RS250 Challenge Cup Racer for sale with just 664 miles!

From the seller:
1999 Aprilia RS250 Challenge Cup Champion

Price: $12,500

This is a 15-digit VIN Aprilia Factory Race Bike. John Hopkins (Hopper) won the U.S. Aprilia Cup Series Championship on this bike while racing for John Ulrich’s Team Hammer/ Roadracing World in 1999. Aaron Clark (of “Clarkie Tuono” fame) rode this machine to win the title at the Daytona ROC in 2000. The bike only shows 1068 KM’s / 664 miles.

I Purchase the bike from Team Hammer in 2002. It has been preserved in its original, glorious race-bike condition from when I received it 20 years ago. Although I start it and move it around a few times each year, It has not had any additional miles put on it since I acquired it (sans a stealthy ride around my old subdivision). It’s been properly stored inside my climate controlled shop. It’s a bit of a time capsule and I love it for that. I hope you will too.

More from the seller:
Being a factory, built-for-racing machine, it is not currently street legal. Original certificate of origin through Aprilia and Pro Italia Motors (Glendale, Ca) plus a bill of sale will be included in the transfer.

The sale includes all the spares and manuals that I received when I purchased it, please see the photos regarding those items. Original rear-stand included as well.

The bike is in very good condition. Essential, non-dispensable components like the frame and suspension parts are in great shape. There are minor scuffs on the right side bodywork and a very small spot on the lower of the two Arrow mufflers. In my opinion, they are just enough to give it some character without feeling the need to further repair. The bike is incredibly good looking.

I Could write a long dissertation about the history and features of the Aprilia RS250 Challenge Cup but I feel it’s safe to assume that if you are here, you already know!

More from the seller:
A bit about Hopkins himself:
During and after the ‘99 Aprilia Cup Championship he went on to compete in AMA 600 Supersport, AMA 750 Supersport (Champion), Formula USA Superbike, Formula Xtreme (Champion) and then of course, MotoGP, Including finishing fourth in points in 2007 with only Casey Stoner, Dani Pedrosa and Valentino Rossi ahead of him. Then World Superbike and British Superbike (where he racked up 5 wins). He was featured in the 2003 documentary film “FASTER” and later “The Doctor, the Tornado and the Kentucky Kid” in 2006.

It’s not every day that these bikes become available and for this one, it’s the first time in 20 years.
Here’s your chance to own a little slice of road racing history.

Go for it.

Price: $12,500


This amazing piece of racing history and heritage is currently for sale. While we do see Challenge Cup bikes come up for sale occasionally (many being converted and masquerading as street machines), none have had the star power or provenance of this one. And who would imagine you could purchase a Team Hammer race bike through a Roadracing World magazine advert back in the day?! The best part is this isn’t some trashed or used up bike – when John M. peeled away some of the black vinyl covering up distracting elements of the dash (such as the speedo), the odometer only shows 664 total miles! This is truly an amazing find, presented in “as it was raced” condition. Thank you John for supporting RSBFS with such an interesting chapter of motorcycling history!

Featured Listing – 1997 Suzuki RGV250/SP VJ23 by Speedwerks

Today’s Featured Listing is brought to us by longtime RSBFS sponsor and supporter Speedwerks. If you are not familiar with Speedwerks, they are a shop based in Delaware that for nearly 30 years have turned out beautifully prepared and restored examples of bikes that we all drool over. If you don’t believe me, check out their shop directly (www.Speedwerks.com or www.facebook.com/speedwerks), and for some history, check out some of the Speedwerks bikes that have been featured over the years on RSBFS: Search Speedwerks.

Featured Listing – 1997 Suzuki RGV250/SP VJ23 by Speedwerks

The RGV250 world changed with the introduction of the VJ23. The last of the RGV series, the VJ23 introduced an entirely new configuration for the two-stroke twin cylinder, affecting the remainder of the overall package dramatically. Gone was the popular 90 degree v-twin that powered the earlier VJ21 and VJ22 series bikes. In its place was a more compact 70 degree unit. Displacement was still 249cc, but that displacement was achieved by a square bore-stroke ratio, as opposed to the earlier models which had a bigger bore and less stroke (over square). The new motor fit more optimally in the twin-spar aluminum frame, providing better handling with improved weight distribution. Suspention consisted of an upside down front fork and rising rate linkage in the rear – both fully adjustable. Electric start was included in the package (no more kick starting or bump starting), and even with such luxurious appointments the whole package still came in under 300 lbs! The SP designation adds even more tasty goodies, including a close-ratio 6-speed gearbox driven by a dry clutch.

From the seller:
This 1997 RGV250/SP VJ23 is by far the nicest, original one we’ve had come through here. There are no stories, no Chinese panels and no excuses’. The Pic’s speak for themselves. We discovered this VJ23 with the help of our friend Rick Deegan of RMD Motors in Japan.

We’ve bought and sold a lot of bikes and Vehicles through Rick/RMD and although he’s a bit ‘Colorful’ at times, he has always been honest and straight forward regarding the machines he sells, this one is no exception and doesn’t disappoint. We struck a deal and purchased it earlier this year. This Suzuki has had only ONE Original Owner in Japan and the gentleman bought it brand new as a 1997 model year. This was a leftover and it was first dealer registered in the year 1999.

In his ownership he racked up 11,900 kms. installed a set of WRS rear sets, kept it serviced regularly, otherwise it’s remained original and unmolested. He was fortunate to have a large house with a garage, where this machine was kept from the harsh salt elements that plague most aluminum and steel on the Japanese island. Consequently, there is none on this chassis.

More from the seller:
The Japanese Documentation is included, along with the 2 Dealer Keys, Manual, Warranty Book, and Factory tool kit.

As evident in the photo’s we did an extensive time consuming service and a borderline OCD detail job on the Chassis. The body is original, shiny and beautiful. All fluids, Fuel system, Carbs, Plugs, Air, Gear Oil and Coolant. The front suspension was also refreshed with new seals, bushings and Bell Ray fork oil. Rear shock refreshed and checked.

Finally a new set of Dunlops were spooned on and this beautiful RGV/SP is ready to;
– add to your collection.
– blast thru the canyons to Alice’s for lunch.
– Use a daily/Sunday rider.

Enclosed, Private delivery is available in the Cont. USA. and included at $24,000.
We can also crate the machine and assist with air or sea freight anywhere in the world.

Asking Price: $24,000
(price includes personal delivery in the continental US – no risky shipping companies!)

As highlighted, this is a home market VJ23 imported directly from Japan. That means that this particular example is restricted in terms of power output. This affects any Japanese home market bike, as the government imposed power limitations in order to curb high-speed street riding. Suzuki did produce these models for export outside of Japan, and those bikes do not have the power restriction. Steve from Speedwerks notes that full power export models will have a black VIN plate riveted to the right side of the frame, just behind the neck, a non-restricted ECU, a modified airbox, a 240kms speedo, and a black cap on the rear master reservoir. If you are shopping for a full power model don’t give up: Speedwerks has one available for restoration with the identical color scheme as today’s home market example (contact Steve for details).

As with all the bikes we have seen come out of the Speedwerks shop – whether they are race bikes or really rare gray market examples such as this 1997 Suzuki RGV250 SP – this bike is immaculate. It has a wonderful back story as a one-owner ride, and the numerous pictures show what is perhaps the best of the VJ23 breed we have seen. As the last series produced by Suzuki, these are rare and sought after bikes. The SP configuration is the one you want, and with only 7,300-ish miles showing this one looks like it will bring joy to a new owner for many years to come. Did I mention that this is the LAST of the factory two strokes ever offered? How about electric start? The best by Suzuki presented by one of the best shops we know, Speedwerks is now offering this exquisite example of RGV250 SP VJ23 imported goodness for an asking price of $24,000 (includes deliver in the continental United States). Here is a link to all 100+ photos of this amazing machine. Contact Steve directly (steve@speedwerks.com) for more details. Good Luck, and thanks to Speedwerks for being such a long time supporter of this site!

Clean and Original – 1986 Yamaha RZV500R

If the RZ350 earlier this week didn’t wake you from your four stroke stupor, then perhaps another 150cc and 2 cylinders of even more smoking goodness can rouse your interest. In today’s post you will find what looks to be a museum quality home market RZ500 – the aluminum framed, restricted output, ultra rare RZV500R.

1986 Yamaha RZV500R for sale on eBay

Today’s bike looks like a museum piece or a time machine (without the flux capacitor, that is). The photography is exquisite, and it is a pleasure to view such a rare machine kept in this type of condition. Note that there are 7,000 KMs on the clock of this bad boy – which means that it accumulated approximately 4,500 miles to date. That is only 125 miles per year since birth. If we could all be so lucky!

From the seller:
1986 Yamaha RZV500R
Bike is in excellent condition with just only 4000 miles or 7000 km.
It still has the new frame protection stickers on each side.
100% original and untouched.
Bike is located in Lisbon – Portugal. Shipping can be arranged.

If you read the seller’s text, you will note that this beauty is NOT located in the States. That is not surprising, as not many RZV500R examples made it outside of the home market of Japan. This particular bike is located in sunny Portugal, which seems like it could be a perfect opportunity for that European riding vacation you always wanted to take. What could be better than tooling around the back roads of Portugal and Spain on such an amazing machine as this?? Keep in mind that if it is 100% original it will be restricted for home market use, so only about 65HP will be on tap. Still, I suspect most shoppers for this one will not plan to put too many miles on it for fear of damage; after all, it looks pretty near perfect in the pictures. Price is set for $25,000 USD with the seller open to offers. You can check out all of the details here. Good Luck!!!

Re-Californication: 1984 Yamaha RZ350

The Yamaha RZ350 was the last of the federally imported two strokes into the EPA-heavy state of California. With precise oil injection, the Yamaha Power Valve System (YPVS) to maximize efficiency, and air-injection and catalytic converters in the exhaust stream, this was the cleanest factory smoker on the planet in 1984. Sadly this was not enough for California, and the bike lasted but a year in that market. The RZ350 still sneaked through emissions in other states however, before Yamaha pulled the two stroke plug in America one year later. Today’s example is a nicely refurbed bike in California that shows some miles and a whole lot of care. I’ll let the seller pick it up from here.

1984 Yamaha RZ350 for sale on eBay

From the seller:
Yamaha RZ350L1984 Kenny Roberts Replica

The bike was purchased as non runner earlier this year. It had sat since last registration in 2016.
The bike ran when parked, but of course was parked for a reason!

Thousands have been spent to re-commision this lovely RZ. It starts first/second kick, pulls all the way to the red line and sounds as an RZ350 should. This will make a great rider, it does have some wear and tear which we have detailed. A good honest bike that just needs to be used and enjoyed. All the hard work as been done!, bid with confidence on this appreciating classic.

Clean CA title – currently registered.
15300 original miles.

More from the seller:
History: A considerable amount had been spent on the bike by the previous owner around 2015-2016 which, included engine work at RZ’s Unlimited of Glendale.

Work completed includes:
Crank Rebuild
New Crank Seals
New Pistons, rings
New water pump
Y Boot & K&N
Spec II pipes
Carb jetted to suit above
Telefix Fork Brace
Stainless Braided brake lines F&R
Penske – full adjustable rear shock with remote

An RZ350 owners manual is included along with a few old receipts, showing purchases of pipes, fork brace etc.

The RZ350 market remain a hot spot for bikes in clean condition. Prices are ever-so-surely climbing – especially for bikes in good or exceptional condition. This is not an NOS stock example, having been rebuilt and slightly hot-rodded with Spec II chambers and jetting. But in many ways THIS is the type of RZ you really want. Bikes that have been woken up by the cat delete and mild performance work are snappy and fun, being both lighter and more powerful than the museum correct examples. And with a relatively recent rebuild and some nice chassis add ons this RZ is ready to spread the popcorn sound of joy throughout the neighborhood and surrounding canyons. Nearly a week left at auction and the reserve has already been met, so don’t miss out! This bike is well presented and beautifully photographed. Check out all of the details here, and Good Luck!!

Good From Afar – 1984 Yamaha RZ350

Just a quickie post on a potentially interesting mystery bike for your weekend reading and researching. It is listed as a 1984 Yamaha RZ350, and these are always fun bikes to post about. The fan base is rabid, and these are getting more and more rare as time passes. In today’s case the mystery is less about what the bike might be, and more about the condition. There are only the 3 pictures, and scant info from the seller. Still, with a price in the basement for the model – and the potential for some real upside in terms of what is on (or in) the bike – there is a lot of interest in this one.

1984 Yamaha RZ350 for sale on eBay

From the seller:
Runs great. Starts with one kick. Has sun fade. Gas tank is clean on inside but outside needs paint. Tires are old. Power wheelies in first and second gear.

Sure, it appears to be well used, if not a little beaten up. It also has a set of chambers, but no info on what else. There has been a lot of bidding thus far, and this one is definitely going to a new home at the end of the auction. You can check out all the details here. Good Luck!!

1985 Yamaha RZ500 in Toronto

Here’s a really clean Yamaha RZ500 with less than 10k miles! We always celebrate the RZ500 on RSBFS because it was of course never officially offered in the U.S. and really represents one of the most collectible two stroke models of the era. The engineering and packaging represents the best of the industry in 1985 and is head and shoulders above more pedestrian sportbikes of the year. 37 years later, it still provides an amazing and powerful riding experience. This example is in Canada and the seller has identified a shipping company that will assist with the paperwork to the U.S. Good luck to buyers and seller!

Happy Friday, -dc

Short and Quick: 2003 Derbi GPR 50 Grand Prix Replica

A bit of a fun one for your perusal. Famed small-bore manufacturer Derbi offered a line of 50cc GP racer replicas as street bikes. Different from the popular Yamaha YSRs, the Derbis were very nearly full-sized motorcycles – except for their engines, of course. This makes them excellent trainers for young riders looking to move up to a bigger bike in the future, and means that they are excellent toys for grown up kids who still love to zing a smoker up past redline occasionally. I’m too busy doing a crank rebuild on my Kawi AR50 to point fingers at anyone in particular…..

2003 Derbi GPR 50 for sale on eBay

From the seller:
DERBY GPR 50 in original as new condition. Has been stored in my climate controlled showroom since new with an occasional ride. 178 miles on the clock. These bikes are used in Europe by riders as young as 14 to train for GP racing. The engine is a 50 cc two stroke with electric start, oil injection and water cooling. Putting out 15 hp at 11,000 rpm and with the six speed transmission it has a top speed of 65 mph. They are originally sold as restricted to 30 mph, this one is unrestricted. GPRs are almost the size of a typical sport bike and are suitable for anyone up to around six feet tall. This bike is sold with the original factory certificate of origin, see photo, and a bill of sale.

These are legitimately fun bikes that are also legitimately rare. The limited capacity and performance keeps them off major roads and highways, and also limits the value appreciation factor. Bad news if you are hoping this will appreciate like an RZ350 or 500. Good news if your man cave is dying for something to fit perfectly into that corner, and can come out for some street hooning or karting track day fun on a sunny day. Not many days left on this one (will be gone by the end of the weekend) and the high bid is less than $2500 bucks, but there is a reserve in place which could spoil the party. Something this much fun is always worth a look, which I thoroughly encourage you to do (besides, I don’t want to be alone in my tiddler obsessions). Check out all of the details here, and Good Luck!!
