Hamamatsu Homolgation:

1989 Suzuki GSX-R750RK/RR in AUS


Back in the last 1980's, WSB and even MotoGP bikes were required to be based on production bikes that were available to the public.  This requirement was known as the homolgation rule and it required at least 50 street legal motorcycles had to be available to the public in order for the same bike to be used as the basis of a race machine.   Perhaps the most famous of these homolgation bikes are the RC30 and OW01 but other efforts include the Harley Davidson VR1000 (of which only 50 were produced for public use) and the Suzuki GSX-R750RK.

The 1989 Suzuki GSX-R750RK (also known as the RR/repli-racer) was a true "straight-out-of-the-crate" racer that was technically street legal but could easily be converted for racetrack use.  In a sign of its true homolgation nature, only 500 of the 1989 GSX-R750RK/RR were produced and they were only imported into countries where motorcycle racing had a significant following.  As was typical for homolgation bikes, most were snapped up by deep pocketed privateer racers who took them onto the track so finding one in good/OEM condition is a rare occurrence.

For anyone not familiar with the RK/RR, the bike had a significant number of upgrades from the standard model

"The RR received a new 40mm Slingshot carburetor, a 4-into-1 exhaust pipe, a close ratio gearbox, new rear swingarm and sub frame, new aerodynamic fiber bodywork with large air intake duct, solo seating with race number box and a 19 liter aluminium fuel tank as standard equipment. The dry weight 411lbs and 120hp at the wheel rivals some modern sport bikes to this day.

The RK  was designed to be a bike which could be tuned easier than its short-stroke predecessor. Racing teams which were already adept at tuning the long stroke engine and so were more familiar with this revived long stroke design,   The newly redesigned engine reverted to the original long stroke (70 x 48.7mm) configuration. Crankcase, crankshaft connecting rods and clutch were among the critical areas receiving more attention necessary for the race duty." 


This particular 1989 GSX-R750RK/RR is located in Australia and looks to be absolutely pristine.  I suppose the condition isn't that surprising given that the seller lists mileage of only 1,990 miles and states that it has never been raced.  All the pictures seem to show a bike that is in absolutely perfect condition, with a unblemished triple tree/fork top as well as an exhaust canister and engine area that look like they were just assembled in the factory.


Is this bike worth the $26,000 AUD/19,500USD asking price?  As the old magic eight ball would say, all signs point to Yes.  While prices for bikes with a production run of only 500 units are hard to figure, the few previous ones we have had on RSBFS for sale have all gone for more than this and condition of those listings weren't nearly as good as this one.  Also the price for this GSX-750RK one seems to be right in line with other top shelf homolgation efforts of the same era such as the RC30 and OW01.

Based on the pictures attached to the auction and the bikes condition, I would be willing to bet that the the current owner is a deep pocketed, long term collector who wants to cash out his investment.  However I do think this one still has some room to appreciate in value;  this is probably the best condition GSX-R750RK we have ever posted here on RSBFS and its unlikely we will see one in better shape than this one for quite a while.   I can honestly say if I was in AUS right now or was confident I could arrange shipping and import to the USA, I would be giving this one serious attention.


Note: This one will probably sell quickly so act fast if you are interested.

5,000 Mile Time-Warp: 1993 Honda CBR 900RR for Sale

1993 Honda CBR900RR R FrontHonda's first-generation CBR900RR, known as the "Fireblade" in Europe, set the stage for today's bleeding-edge literbikes that see the most powerful engines ever stuffed into tiny, 600-class packages. Prior to the 900RR, it was the 750cc class that really defined the "big engine in a small chassis" philosophy, with 1100cc motorcycles designed more as GT machines, rather than light, flickable sportbikes. Sure, they made plenty of power, but they were generally much heavier and nowhere near as nimble as their smaller siblings. 1993 Honda CBR900RR L SideBut the Honda CBR900RR, introduced in 1992, turned the whole sportbike world on its ear. They built their new bike around a 750cc package, but stroked the motor out to 893cc's to give big bike torque, along with screaming revs. The machine weighed in at 453lbs soaking wet, which made it bang on for the 600cc class and within a few pounds of Honda's own CBR600. So what the bored-out 750 gave up a few horses to genuine "literbikes," it gained back in power-to-weight. 1993 Honda CBR900RR FrontObviously, no one would have considered the CBR "rare" back in the day. But most of these have been badly used and abused, crashed, modified, stretched, lowered, or repainted, making a very original, almost impossibly low-mileage example like this one very rare indeed.

From the original eBay listing: 1993 Honda CBR900RR for Sale

This machine is super clean and in great mechanical condition.  It has super low miles (I can’t remember when I last saw one for sale with such few miles) and is completely original and stock (aside from things like the tires).  The machine has gone through a complete service which includes Carburetor service, new tires, new battery, etc..  There are no known mechanical issue with this motorcycle.   I ride it about once a month right now and did a 70 mile loop recently and it ran like new.

Fell free to reach out with questions at

100% Original and stock (including handgrips, turn signals, exhaust, seat, etc...)
Less than 6k miles.
Historical significance / important bike in the Honda line up
Collectible / Rare to find one that is original and in this condition.
No cracks or breaks in the fairing
Completed tune up and service
Brand new tires with less than 200 miles on them
New battery
Carburetor Completely cleaned
Runs excellent
Clean Title
Always stored indoors
Only selling because I have three other bikes and this one is the one I ride the least

Cosmetic Imperfections only (see pictures):
Small ding in gas tank
A couple scratches in fairing and decals
Paint on exhaust is coming off

Problems for today's rider? Not many: in typical Honda fashion, these are extremely durable and reliable bikes when cared for. And the 16" front wheel that was intended to speed up steering now makes tire choice a bit of a pain, although there are options available and you can always swap the 17" front from a VFR on, a switch that requires no modifications.

1993 Honda CBR900RR TankI happen to love this particular body style, although paint schemes are typically 90's lurid: you either love them or you hate them. I just wish they didn't hide the neat bodywork details, like the vents in the tail and those "speed holes" in the fairing. 1993 Honda CBR900RR R Rear

Currently, the bike sits at $4,500 with the Reserve Not Met. While the same cash will net you a whole host of other, probably weirder motorcycles, values on these early 900RR's are on the rise, and you certainly won't find a more practical sportbike for your money.

Pocket Rocket – 1988 Honda NSR250R

1988 Honda NSR250R on eBay


The Honda NSR250R should be on everybody's bucket list of bikes to own and ride before they die.  There's nothing that makes you feel like you're living your GP dreams quite like screaming to redline and feeling that 2-stroke powerband change your perception of 250s in an instant.   While 45hp might not seem like a lot (OK, it's not)... there's much more to this bike than just horsepower.  For starters, the NSR tips the scales at just 315lbs wet.  So next time you're at the gym, pick up 135lbs and realize that's how much LESS the NSR250R weighs than a typical 600cc sportbike.  With it's light weight, attention grabbing powerband, narrow frame and short wheelbase, you begin to understand why these little 250s are a force to be reckoned with when the roads get twisty.  And then there's the sound... that glorious, glorious sound.


The MC18 model here is the second generation of the NSR250R and it saw significant improvements.  The carb is 4mm larger and the engine management is improved for better throttle response over the earlier model.  Honda also moved the engine forward and lower in the frame which makes directional changes that much quicker.   The fact that these little gems were never officially imported into the US means that customs paperwork and titles can sometimes be an issue... but all of the hard work is done here.  The seller states that it already has a US title, has new fairings and comes with a generous assortment of spares.  So if you're looking for a hassle free 2-stroke 250, now might be the time!  You can check out the auction here: 1988 Honda NSR250R on eBay

From the seller:

Very clean Gray Market Street Legal 250ccTwo-Stroke Sport Bike. Imported from Japan in June of 2000. All stock. Runs, idles, rides and stops as it should. Very strong pull when it hits the power band. No damage, rust or corrosion anywhere. All new fairings and paint on tank. Also includes original fairings and many spare parts including brand new brake pads, extra rotors, calipers, fork assy, speedo and more (see photos). The spare parts are included with the sale.

1st time on RSBFS: Laverda Black Strike 668 in the UK


Here is one we haven't had on RSBFS previously, a Zane-era Laverda 668 Black Strike.   The Black Strike model incorporated all the top shelf goodness of the Laverda marque at the time; a Nico Baker designed frame, 3 sets of brembro brake calipers, Marchesini wheels and a letterbox gas tank that reduces the center of gravity (which is still pretty advanced after 14 years). And the fact that you can still get a Zane-era Laverda for reasonable money whereas a lot of Breganze-era bikes have begun to appreciate beyond the reach of us mere mortals is another plus.

Note:  For anyone not familiar with the Zane-era vs Breganze-era Laverda models, click here for a brief overview.


Laverda 668 Black Strike in the uk

The black strike edition was a kind of a one-off within the Zane-era lineup; the air-cooled 668 engine and Nicco Baker designed frame were from the 668 sport model, while the seating and gauge clusters where from the the 668 ghost. The 668 black strike was also the first model with the lighter plastic gas tank, straight exhausts without the restricted collector box and also offered a few bits of optional carbon fiber such as exhausts and optional front fender/mudguard.

This particular Zane-era Laverda 668 black strike looks to be in excellent but not pristine condition.  I can see some minor bits of weathering included some fading in the small side cover panel above the id plate, what looks like some dried polish or flaked off paint on the riders right engine cover and some evidence of brake fluid removing paint on the Marchesini rear wheel.

On the plus side, the pillion cover is in place and looks to be in good condition and the seller indicates both the standard and carbon fiber versions are included for both the front fender/mudguard and exhaust. This is important since all 3 items are pretty much unobtainable nowadays. Also while the "rabbit-ear" standard mirrors are missing from the pics, the seller indicates these are included and the often missing rear plastic hugger/mudguard is in place.  Lastly the seat condition, lack of bubbling in the dash light decals and lack of rust on the dash nuts/bolts all seem to indicate proper storage away from both the hot sun and damp during non-riding time.


Here is what the seller has to say:

  • Has done 17,235km,
  • Currently has the front carbon mudguard on but I have the original in great nick that comes with it,
  • Also have the original exhaust pipes but currently have the carbon exhausts on.
  • There is a carbon windshield that is with it that I thinks off a ghost legend.
  • Side mirrors are with it but I preferred it without.
  • Battery currently not with bike but will be added before sale.
  • Had a new speedo cable 100km ago, new oil just put in.
  • Rear tire has done 200km (maybe just less, looks like new), front had good tread also.

Note:  The seller lists this as a 2001 but the black strike model was produced from 1997-1998.   Email messages with the seller indicates that the 1st registration was 2001 hence the date.  I would guess this bike is actually stamped a 97 or 98 on the manufacturers id plate which is mounted on the riders right side but was probably in a showroom for a few years (Three Cross or Slater Bros dealerships perhaps?) and was only sold after Laverda was absorbed by Aprilia/Piaggio.


Is this Zane-era Laverda 668 black strike worth the 3,400GBP asking price?  Well only 50 668 Laverda Black Strikes were produced and since Laverda is now a mothballed marque within Aprilia/Piaggio this is definitely a rare bike.  But the 668cc air cooled engine produced about 70 bhp so its not going to blow the doors off any other bike and some zane-era bikes have had reliability issues with electrics and cranks so the status of these items which would need to be factored in to the price.

To be honest, I think the the current asking price is a bit high but not outragously so.  While the Zane-era laverdas seem to be starting to appreciate, I think the value for this right now is probably closer to 2400-2850GBP.   I do think these will appreciate in value going forward so the bike may be of interest for a UK-based collector looking to add a bit of Zane-era exotica to their collection.


Addendum:  I feel it only fair to let readers know that I have a restored 668 Black Strike in my personal collection.

Blade Runner – 2007 Bimota DB6 Delirio

The late designer Sergio Robbiano's upright response to his Bimota DB5, the DB6 Delirio is a motard variant, an urban sportbike based on the Ducati 992 desmodue.  Factory-made but hardly mass-produced, the Delirio has inspired design, innovative solutions and superb components.

20150629 2007 bimota db6 delirio left front

If the trellis frame of the Delirio appears unusually light, Bimota used chrome-moly tubing, showing off some of the thin edges.  The distinctive billet aluminum connectors for the frame and rear wheel complement the red frame.  The body is an angular combination of metal and plastic, complex without being busy.  Just 400 lbs. wet, the Delirio requires just a thought to change direction, the Marzocchi suspension always ready.  Braking by the Brembo 320mm wavy front disks and 4-piston calipers is outstanding.    The alloy Marchesini wheels are light and black to the point of invisibility.  The futuristic headlight fairing integrates the turn signals and has its own billet brackets.

Asking nearly $30,000 when new, the DB6 is a design piece, every detail examined, drawn, tested.  On this one, only the exhaust has been upgraded to a Zard carbon system.  With just break-in miles since 2007, this bike looks perfect but will likely require new fluids, belts, and rubber.  From the eBay auction:

This is a beautiful Bimota DB6 Delirio in excellent condition.  Zard carbon exhaust.  Rare and exotic, incredible workmanship and detailing, just 1,787 original miles, a Ducati at heart, but much more!  Condition: Excellent-Bike shows like brand new.

There are more rare and exotic Bimotas, even special Delirios, as there is an Azzurro model ( think blue ) and a Superlight with full carbon frame, but this "base" model has all the design elements, just about all the performance, and most of the exclusivity.  A dream compared to the wide majority of naked bikes.  Hoping those frame sliders never get used !
