Just in Time for Halloween: 2012 KTM RC8R for Sale

In spite of very positive reviews, the RC8R, KTM's Origami Superbike, never sold well. Some feel it was that the original iteration wasn't quite ready for prime time, with a power deficit and a crunchy gearbox, along with some pretty basic electronics, compared to Ducati's 1198. The bike's high price tag probably didn't help things either. The second generation seen here addressed the first two issues, but the bike was always an analog holdout in an increasingly digital class.

Maybe it was that the people that buy superbike riders are a snobby bunch and didn't want to take a chance on an expensive new machine built by a dirt bike manufacturer. Or maybe they just aren't fans of orange. You'd think they'd have gotten the message that the bike would perform, since KTM's earlier 990 SuperDuke and Supermoto had gotten pretty good reviews. The heart of the beast was an updated version of those bikes' liquid-cooled 75° v-twin that originally displaced 1148cc in the RC8, although it was later increased to 1195cc for the 2010 RC8R model, with an output of 175hp and a pretty massive 90 ft-lbs of torque.

It didn't compete against the class leaders when you compared spec sheets, but the KTM was never really about the pure numbers or technology simply for the sake of it. It was designed to actually function as a motorcycle, and the bike's adjustable ergonomics were intended to work for a wide range of riders and riding styles, from dedicated track day junkies to casual weekend sportbikers. These were difficult to shift when new, but have managed to hang on to their values on the used market pretty well. Those few folks that bought them seem to love them and I think people realized quickly that the RC8R would eventually be considered a classic.

There's Something About That Listing That Bothers Me, But I Can't Quite Put My Finger On It... We surely all feel the pain of tire-kickers and looky-loos, and you'd better believe I agree with the seller's last line, but I'm pretty sure people that do that stuff won't be deterred by anyone putting "no BS" in their listing. Sort of like putting "no players or married guys" in your online dating profile... And the list of service and parts is nice but that "new rear rotor".... sorry: "New Rear Rotor" makes me a little nervous. How the hell did that happen? Anyway, at $11,000 this isn't the cheapest or the lowest-mileage RC8R I've seen for sale recently, but it's a clean example and those striking colors fit my Halloween theme.

Derbi October 12, 2018 posted by Tad Diemer

Featured Listing: 2005 Derbi GPR50 for Sale

Considered a moped for legal purposes, today's Featured Listing Derbi GPR50 looks like a real motorcycle for the most part: liquid-cooling, electric start, full fairing, 17” wheels, under tail exhaust, six-speed gearbox, aluminum frame… But then there’s the lawnmower-sized 50cc displacement. From the factory, you were looking at 8.8hp at the crank, or around 5.5hp at the wheel. Normally, I scoff at partial horses, but every single pony counts when you’ve got just 49.9cc to work with. The same thing goes for the .9cc displacement, obviously.

The hydraulic brakes work well, especially considering the GPR50's light weight, but you certainly won’t need them to slow down too often: the bike takes care of that for you by not being fast to begin with. Obviously, top speed isn't the point with a bike like this, and the parts are there to maximize the limited power: that six-speed box means you can stay in the meat [tofu?] of the powerband and, while the suspension is pretty basic, a 242lb weight and great geometry mean a GPR50 could be pretty fun on a tight road or go-kart track.

This example has been modified with a 77cc "big bore" kit that should take the bike to around 9 horses at the rear wheel, but the bigger jump should be in torque: the stock bike makes around 4 ft-lbs and a kitted bike like this should be closer to 7... Performance data for the GPR50 is pretty scarce, but a Cycle World review of the mechanically similar 2000 year model with the same kind of displacement upgrade claimed 60-65mph on level ground, with 75mph possible, flat-out in sixth gear, using a bit of drafting…

From the Seller: 2005 Derbi GPR50 for Sale

For sale is a US spec (MPH speedometer) 2005 Derbi GPR50. At one point this bike was imported to Quebec Canada, and the present owner has had the bike for the last 6 years. Due to the fact that this is registered as a 50cc, and it was plated as a  Scooter. We still have the Quebec registration that states its a "CY" (cyclomoteur = scooter). PLease check with your own state laws, as it differs from state to state. 

The Derbi GPR50 is a single piston two stroke 6 speed water cooled bike. Inverted forks, and monoshock rear suspension. Electric starter and weighs in at about 220lbs. The Derbi GPR50 up for sale in Montreal Canada, and has about 12,000 miles (To be confirmed; battery will be changed to access mileage) bike was totally rebuilt in 2014. 77cc Airsal cyl. Top racing crankshaft, 21mm carb. Arrow exhaust/expansion chamber, clutch and reeds from Malossi, new chain, new sprockets, and tires. bike was used for about 1800 miles since rebuild, and has always been sitting inside our climate controlled garage. It has not been used on the road since about 2 years. Bike has a few scratch from a small miss hap in 2014, and a few blemishes from being a 13 year old bike. Besides that , in extremely good condition , and will reach about 70MPH in 6th.

Needs a battery (we will put a fresh one in), and the clutch could be refreshed. Bike has an electric starter. Asking $2,900USD firm, will crate, and assist in shipping, but shipping to be arranged, and paid by the buyer. We have the clean, and free of lien registration, (which is the same as your Title).
Originally a US import, so gauge in MPH. Paypal for initial deposit, but bank transfer is the only way we will ship the bike, unless you pick up with cash. This is a private sale, feel free to contact the seller, at his place of business for more information.

Obviously, a GPR50 is more a toy than an actual transportation device, even with the increased 77cc displacement, at least in most of the United States. But for $2,900 this could make a great urban runabout, or a massively overqualified but very stylish pit bike. Or maybe you've got a youngster looking to start a racing career?

Bimota October 10, 2018 posted by Tad Diemer

Master’s Thesis: 1992 Bimota Tesi for Sale

Throughout the history of the motorcycle, there have been many attempts to develop a superior suspension system, and the hub-center steered Tesi or "Thesis" was Bimota's attempt to radically alter the sportbike landscape and do something completely new, a shocking move for such a tiny company. The ubiquitous telescopic forks have a number of disadvantages, chief among them geometry changes caused by "dive" under braking: the fork tubes compress, steepening the steering. This can theoretically be used to your advantage, but the "stiction" or friction between the sets of sliding tubes certainly can't. But so far, telescopic forks have proved the best compromise and engineers clearly understand their limits, so they persist as the most common way to suspend the front end of a motorcycle.

The only manufacturer to really buck that trend recently, at least in significant volume, has been BMW. But their Telelever front end is being used less and less, owing to a different concern: radiator placement, since the front "A-arm" of the Telelever system takes up the space where one would normally reside. Bimota got around this issue by using an "Omega" frame that allowed the front swingarm pivot to be very low to the ground,  so a pair of radiators could sit easily above. The frame gets its name from the two Ω-shaped machined aluminum side plates that sandwich Ducati's liquid-cooled v-twin. Originally a stock 851 motor, it was eventually stroked to 904cc after the first batch of bikes was built.

Unfortunately, the Tesi's steering linkage was complicated and expensive to produce, and any improper adjustment or slop in those joints caused steering feel to suffer, something that seems to be an issue with alternative front ends in general. BMW's Telelever front is famously stable on the brakes, but has often been criticized for a lack of front-end feel, although a set of Öhlins shocks at both ends supposedly improves things. The Tesi had the same reputation: it was wild and exotic, and test riders could brake deeply into corners with confidence, but the bike lacked a bit of feel, even when everything was working as designed. Which took some doing, given the relatively complex system connecting the clip-on bars to the front wheel.

The other issue with the Tesi is a bit more theoretical: a swingarm front end should be much easier on front tires than a bike with a telescopic fork , allowing the Tesi to run a much softer compound tire without experiencing the same wear. But manufacturers design their tires to work with telescopic forks, so one hypothetical advantage is lost there as well, unless systems like this become more common.

But the biggest issue with the Tesi was its high cost: for practical purposes, it was just a Ducati 851 with cool bodywork. All that engineering had very little impact on performance, making it more of a stylish statement of intent than an actual improvement. The Tesi name is very apt: the original bike literally was a graduate thesis project, and was built around a Kawasaki GPz 550 engine. Bimota's prototype was built around a V4 Honda, but that proved to be too wide, so the production model went to the narrow and powerful Ducati v-twin.

From the original eBay listing: 1992 Bimota Tesi for Sale

Somewhat challenging personal circumstances are forcing us to undertake this unusual listing and one-of-a kind sale, so we are now offering this, our lovely NOS 1992 Bimota Tesi 1D904SR starting at $1 without any reserve.

To be absolutely clear, THE HIGHEST BID will purchase this very rare and exceptional motorcycle, no matter the final value.

We had hoped to hold onto this gem for a few more years and wait until the worldwide Bimota market has improved and collectors and enthusiasts alike have come to realize how rare and exceptional some of these bikes and specifically the Tesi really is. Sadly health related problems and financial issues force us to take this step now and sell his rare and unusual motorcycle, hopefully to a likeminded enthusiast.

So there is no misunderstanding, please be so kind to have your finances in order and be able to pay for this motorcycle when the auction is finished, however high or low the final value amount may be. An immediate $500 deposit is expected from the winning bidder upon winning this auction, the remaining outstanding amount due upon pickup or prior to leaving our possession no later than 14 days from end of auction. Please prepare for this request by having your paypal account balance reflect the needed amount beforehand and be ready to complete purchase of the bike in a timely manner. Thanks so much for understanding.....

There will be a flat fee charged to have this motorcycle crated professionally and shipped fully insured to any location, worldwide. Of course: If you prefer to pick this motorcycle up in person, or have it picked up by any professional service or freight forwarder of your choice at our location here in Basel, in Switzerland, the entire packing and shipping fee will be waved.

Please look at the shipping details for more information. All else is explained in the description below in detail.

NOS motorcycle, never ridden, never run and properly prepared for long term storage on a pedestal when new in 1992. Specifically ordered and delivered from the factory in this condition. Original in every way as it was in 1992.

Pictured with and without bodywork mounted to show that the exceptional condition throughout is not just skin-deep.

All 3 cast iron Brembo rotors still have the yellow zink plating on the rotor-surfaces to protect the rotors from oxidation while sitting. This coating wears off on the first mile ridden and when the first contact of the rotor with the brake pads occurs.

Hydraulic system, cooling system and the original battery have never been filled with any fluids. The engine is filled with a light oil to preserve internals, seals and bearings. This motorcycle was kept in a climate controlled environment without UV light exposure its entire life, so there has been no deterioration of any rubber pieces nor any age related discoloration of any other parts

This Bimota comes with the original owners manual, warranty booklet, copies of the parts manual and workshop manual and 2 sets of the complete and original Tesi 1D toolkit. This Tesi also comes with both the mph dashboard and the km/h dashboard, both were ordered with the bike in 1992. The original early Bimota Tesi rear stand is also included with the bike

Please only bid if you are serious in your intent to purchase this motorcycle at the end of the 7 day bidding period. Obviously any taxes or duties the buyer has to pay upon importing this vehicle into the country of their choice is solely the responsibility of said buyer

This motorcycle is over 25 years old and hence is fully legal to import into most countries including the USA (EPA and DOT excemptions apply to vehicles over 25 years of age) as of last year!

The bike is currently located in Switzerland, but I'd guess anyone buying this is looking to collect and display, not actually ride this Tesi: it's a museum-piece, but what a museum-piece! Happily, the seller has provided plenty of pics of the bike for us to drool over, since most of us won't be owning or riding one of these anytime soon: less than 200 of the 1D model seen here were built before the updated SR version was introduced. Even better, the bike is shown sans the fully-enclosed fairing that really only allows hints of the weirdness within to peek out, something rectified on the minimalist styling of the current bike.

Sport Production Speciale: 1998 Ducati 916 SPS for Sale

Not many photos accompany today's Ducati 916 SPS, although the few that are suggest the bike is in very good, lightly used condition. A classic homologation special, the bike was designed to move Ducati's production racers beyond the limits of the original 916 engine.

The 916 SPS was the first bike to use Ducati's new 996cc engine that was much more than a displacement bump: it included stronger cases to prevent cracking that occurred under racing conditions, new heads, barrels, pistons, crank, injectors, and was mated to a close-ratio gearbox shared with the 748. This 1998 example also featured lighter frame, titanium connecting rods, and a few other evolutionary tweaks.

1058 were built, making the 1998 model year bikes a bit more common than the earlier SPS and SP bikes, but that just makes it that much easier for ordinary collectors to get their hands on a bit of Ducati's racing mystique.

From the original eBay listing: 1998 Ducati 916 SPS for Sale

Number 396 [of 1098 produced], the SPS was the World Superbike homologation special with the 996 engine. A good description of features can be found at Odd Bike from Feb. 18, 2013. I purchased the bike from Touring Sport in 2004 and I am the second owner. It is titled and licensed for the street -  some are not. It has been maintained by Fast Frank Shockley and Barry Crowe.

It hasn't been down since I have owned it, but has light scratches on the lower right fairing from a fall off the stand [see picture].

It is original except: replacement gas tank [rust], clutch slave cylinder and the hand grips may not be original. The wheels are Marchesinis. The battery was converted to a light weight Earth X.

Inspections welcome at buyer's expense. Seller can be reached at 828.817.9135 to answer questions.

My understanding is that, due to noise requirements, these were never technically legal here in the US, although plenty have been road-registered here at this point: this particular bike is in North Carolina, and the 10,000 miles suggest it's seen a bit of use. Bidding is up over $8,600 with the Reserve Not Met, no surprise since the last couple we've featured have gone for $11,000-12,000.

Very Polished: 1988 Honda NSR250R SP Rothmans Replica for Sale

You are not looking at a Honda NSR250R Rothmans Replica. Sure, it's shaped like an NSR250R, but if you look a bit closer you'll notice something a bit... off. Someone's gone a bit crazy with the metal polishing wheel and, in the process, created something that will surely inflame the comments section. Please try to be polite...

The stock NSR250R frame is welded up from cast and extruded sections, and the main spars are a bit shiny, compared to the cast bits, but they generally don't have this bike's mirror-like sheen. And the swingarm and fork lowers don't generally look like they came from the JC Whitney parts catalog. In the 80s and 90s, polished frames were a bit of a thing, and plenty of Japanese sportbike owners added a personalized touch to their rides by adding a bit of bling. Bikers like shiny things... Unfortunately, collectors are a different breed, and tend to like their bikes very stock.

All NSR250s were powered by Honda's liquid-cooled two-stroke v-twin, and the lightweight Magtek wheels suggest this is a genuine SP, although I can't see a dry clutch in the pics. Certainly a real SP or "Sport Production" Rothmans Replica would be at the high-end in terms of desirability for the NSR250, but all that polishing is going to be tough for many two-stroke fans to swallow.

From the original eBay listing: 1988 Honda NSR250R Rothmans Replica for Sale

This Is a 2-stroke race replica v-twin made for the Japanese market and sold in Japan. It runs perfectly, doesn't leak any fluids, and functions as it should. Starts on 1 or 2 kicks hot or cold. Oil injection works. Leakdown is excellent. All lights and gauges work. Speedo is in km and reads 36072. There is no horn. All fluids have been changed. All wear items,(brake pads, chain, sprockets, tires) are in excellent condition.

 It has been heavily optioned/modified with the following: 

  • JHA pipes
  • Real Balance rearsets 
  • Steel braided brake lines
  • NHK steering damper
  • HRC De-restrictor box 
  • Complete wiring, coils, PGM II ECU out of MC21 model
  • Curved larger radiator from MC21 model
  • Shorai lightweight battery
  • Carbon fiber clip-ons
  • Billet upper triple clamp
  • Front forks rebuilt with cartridge emulators

Buyer pays shipping, will help with crating and delivery to a local shipper for a reasonable fee.

The seller has a starting bid set to the tune of $9,000 and... I have a bad feeling he's not going to get many takers: too many unanswered questions. While many purists may balk at all the bolt-on farkles, they don't bother me. They're not my taste either, but easy to change: you can either spend a bit of time tracking down factory, or at least period-correct bits. Or just some anodized black bits. But however solid the bike is mechanically, it's going to take a particular buyer to overlook that frame, since you're going to have to do some pretty serious work to get it looking stock.

Torque of the Town: 1996 Moto Guzzi Sport 1100 for Sale

With all the 2.3 liter inline triples, 1200cc V4s, and 2000cc v-twin cruisers running around in recent years, 1064cc of pushrod v-twin doesn't sound like all that much muscle. But back in 1996, when you could buy a Moto Guzzi Sport 1100 new, that was a pretty huge motor, especially for a sportbike. Although many might argue that we're stretching the definition a bit here for the Guzzi...

Really though, it's just a different kind of sportbike, one oriented more towards fast road riding and long sweepers than track day scratching or tight canyon thrashes. A more mature sportbike, carrying just a bit extra around the midsection, along with plenty of high-quality components and racing history. I don't just mean ancient history: the Sport 1100 grew out of the bike developed by Dr John Wittner for his privateer racing efforts in the 1980s. A variation of the resulting Daytona 1000 was released powered by Guzzi's two-valve pushrod twin, the Sport 1100 seen here.

Earlier versions used a pair of Dell'Orto carburetors but the bike switched to fuel injection around 1996. WP suspension means the bike has stable handling, once you get used to the mild shaft-drive effect and the longitudinal crankshaft. Triple goldline Brembos lack Guzzi's earlier linked system and haul the 487lb machine down from speed effectively, although you're still fighting 500+ pounds of beefy Italian sportbike with fuel and oil.

From the original eBay listing: 1996 Moto Guzzi Sport 1100 for Sale 

This is a beautiful and rare collectible Moto Guzzi 1100 Sport in true Italian racing red. Carefully maintained through out its life. This rare collectible is part of a private collection and is being sold as is to thin out the heard in the hopes another collector will snatch this elegant red head and love it just as much as I have. 

Australian made Andrews exhaust pipes fitted makies this Guzzi sing. Rev the throttle and this 1100 sport will give you that heartwarming feeling of a by gone era of motorcycling. These bikes rarely come up for sale especially like one in this condition.

Great condition with low miles makes this the one to have. Small ding in front of tank with a loss of paint can be seen in pictures but in all honesty it barely shows unless your looking hard for faults.

18,713 miles isn't even broken in for a Guzzi: these things seem to rack up some pretty high mileage, considering the aggressive riding position.  This one looks pretty clean and complete, if a little scruffy around the edges and is missing the airbox, opting for exposed filter elements instead. The $7,400 asking price seems a little bit high, considering other 1100 Sports we've seen recently here on RSBFS, but not outrageously so. If you're looking for an appreciating, practical classic, look no further. The Moto Guzzi Sport 1100 isn't really any kind of track bike, but it's a great road bike, with stable handling, torque, and good parts availability to keep it running.
