I Think I’m Turning Japanese – 1985 Suzuki RG500G Gamma

Published March 16, 2023 by Mike

Spring has not yet sprung, but the ring-a-ding-ding sounds of our favorite smokers continue this week with a very cool RG500 Gamma. We don’t see enough of these square-four monsters on these pages, and rarer still in the black & red livery. This particular bike is on the ground in Japan, purportedly a full-power example out of Australia. It doesn’t matter to me what flag it runs under, because as an American this is one awesome looking 38 year old piece of forbidden fruit.

1985 Suzuki RG500G Gamma for sale on eBay

The RG500 magic starts with the engine – which is actually TWO engines. Think of the RG as a pair of independent, parallel-twin, 250cc two stokes, complete with independent rotary valve induction (there is a very thin, Mikuni flat slide attached to every cylinder), exhaust and crankshaft. Now stack those two on top of each other, one right behind the other. Connect the two cranks via gearing, and route that whole hot mess through the gearbox. You end up with a very powerful, very compact and dense package that can be placed far forward in the chassis for optimal weight distribution. And speaking of chassis, that would be a double down tube cradle style affair, exquisitely constructed in aluminum alloy. A 38mm, air adjustable front fork and Full Floater single rear shock complete the package.

A full power RG500 is published as 95 HP – which is a fair amount of poke for a sub 350 pound (dry) machine. This gives the big RG its bona fide GP replica status, and general reputation as the fastest of the street-going two strokes. This one is safely tucked away in Japan, indicates nearly 23,000 miles on the KM clocks, and has been cared for and maintained in a manner that allows it to show very well indeed. Paperwork, shipping, taxes and importation hurdles notwithstanding, this auction has an opening ask of $36,500 USD (no takers yet) and a BIN of $48,000 USD. Check out all of the details here – including a walk around video – and Good Luck!!

Blue Haze & Gamma Rays – 1983 Suzuki RGB500 MK8

Published February 6, 2023 by Mike

Located on the eastern outskirts of Tokyo in the Japanese prefecture of Chiba comes today’s ultra rare find: a Suzuki RGB500 race bike. Created by the factory to outfit privateer racers, the RGB500 was steadily improved over the years in the direction of – but always slightly behind – the full factory effort. Still, this was as close as you could get to buying a 500cc GP machine because it WAS a 500cc GP machine, capable of astounding feats of performance with a brave enough pilot on board.

1983 Suzuki RGB500 MK8 for sale on eBay

Like the Big RG500 Gamma street bike that shares its name, the Suzuki GP bike was a big square-four, liquid-cooled two stroke. Power was estimated to be 110+ HP from the rotary disk-valve inducted motor, with most of that concentrated way up near the top of the rev range. Suzuki did what they could to tame the beast via a steel double down tube frame, stout front forks which incorporated a modern anti-dive mechanism, and a rising rate “Full Floater” single shock rear suspension.

From the seller:
It is a very beautiful vehicle.
The aluminum tank is new.
The exterior is all original paint.
Not a repaint.

SUZUKI Works Specifications:

The front fork is a 40mm magnesium square anti dive
Magnesium front caliper
Magnesium rear caliper
Front and rear 18 inch Works Campagnolo XR35/40 Wheels
Resin kill switch
Front and rear works disc rotors: 310mm / 220mm
190mm pitch Works stem: Upper magnesium / Lower aluminum
Magnesium Front Brake Master
Magnesium Rear Brake Master

More from the seller:
All parts are genuine Suzuki race parts.
Most are new parts.
It was assembled with new parts in the picture.
Except for genuine aluminum bolts, they are all titanium bolts.
A very rare RGB500 Racer!!

There is not a tremendous amount of info on this one, but the pictures show a clean and well preserved racer commensurate with the 1980s, in various stages of restoration. The market for these bikes appears to be all over the place, as we do not see these B model customer bikes very often. But imagine the jealousy thrown your way when you show up at a local track day event on this bad boy! Popcorn noises and dry clutch rattle only enhance the experience! This particular bike has a starting bid of $90,000 USD – which is likely scaring away potential bidders as there are zero bids offered at this time. You can check out all of the details here, and Good Luck!!

Featured Listing – 1985 Suzuki RG500 Gamma!

Published November 23, 2022 by Mike

The seller states this 1985 Suzuki RG500 Gamma Featured Listing is a “Street-legal Collectible GP Replica” and he is very correct indeed. The sharpest of the street going 500cc two strokes, the Gamma was the pinnacle of the GP replica set. Showroom statistics aside, this beauty goes quite a bit further than that, thanks to a massive rebuild and performance work done by the legendary Rick Lance. The best part is that this is not a new bike to RSBFS, as we have seen it before on occasion which allows us to track mileage and usage across owners. In short, this is a stunning example of what a RG500 could be with performance far beyond what you might otherwise find, and even includes a signature by Randy Mamola; someone who knows a thing or two about riding a fire-breathing beast.

Featured Listing: 1985 Suzuki RG500 Gamma for sale on eBay!

From the seller:
1985 Suzuki RG500
Powered by a very compact, water-cooled, twin-crank, square-four two-stroke engine that works like a pair of parallel twins geared together. Stock the bike was cutting-edge. Weighing-in under 400 lbs dry and producing 100+ HP at the crank (stock) with typically ‘exciting’ two-stroke delivery, the Gamma was one of the rawest bikes of the period, a true “race-bike for the road.”

More from the seller:
This listing isn’t some all-original barn-find, but was given serious mechanical and cosmetic attention by the late Gamma Guru Rick Lance. It has the following list of mods:
Full motor rebuild including:
555 Big-Bore upgrade
GSX-R Radiator
Maranello transmission kit
Lance Gamma clutch upgrade
Lance Gamma TriPod air filter kit
Lance Gamma supplemental fuel shut-offs
Pipes supplied by Lance Gamma (I believe Rick said the were Jim Lomas pipes in our last conversation)

Chassis, bodywork, etc:
Battery and oil tank relocation
Upgraded wheel/ tire combination (Katana wheels)
Race-Tech fork upgrade
Rear shock upgrade ( FOX, I believe)
Lance Gamma fiberglass bodywork with custom paint scheme
Tank autographed by GP legend Randy Manila

More from the seller:
This is the second Rick Lance prepped Gamma I have been fortunate enough to own and is irreplaceable to me, but life-circumstances change and it is time to let go. I’ve seen several Gammas sell for $30-35,000 and I believe this is highly collectible and nicer than any of them.

Feel free to contact Vinnie @ 920-988-1950 with any questions

With an auction starting in the bargain basement price territory, there has been avid interest in this bike (reserve not yet met). We know this will not stay in bargain territory very long – after all, you are never going to see one as striking – nor as nicely outfitted – as this one. We encourage you to check out all of the details on this one – as well as the archive posts from years past – and then throw your hat into the ring. Suzuki has not built a RG500 for decades, and the glory days of the two stroke is over. Rick Lance, sadly, has left us with a limited number of his fantastic creations, this being one. So move quickly if you are interested – this beautiful 1985 Suzuki RG500 Rick Lance Gamma won’t last long!

Portuguese Perfection: 1985 Suzuki RG500 Gamma

Published April 29, 2022 by Mike

I’m not sure exactly what is going on in the sun-drenched land of fine port wines, but some amazing motorcycles are being cleared out of a collection and all are RSBFS worthy. In today’s case, just on the off chance that you were in the market for a pristine RG500 Gamma with low miles, let us share some of the details.

1985 Suzuki RG500 Gamma for sale on eBay!

The Suzuki RG500 should need little introduction on these pages, but if you Rip Van Winkled your way through the 1980s then a brief refresh might be in order. Designed to be a 500cc GP racer for the street, the big Gamma was of two-stroke configuration and utilized a square four engine arrangement (think of it as a siamesed pair of parallel twins connected at the crank). This was very much in line with the race bike, which was long before the four-stroke days of the current MotoGP. Intake and breathing was via 4 carbs synchronized through disk valves. And since two-strokes are very sensitive to exhaust pressure, the Gamma had four independent chambers; one for each cylinder. The frame of the Gamma was box-sectioned aluminum with castings for the headstock welded on. Front forks were high-tech air-adjustable with anti-dive, while the Full Floater rear suspension made due with preload only. As was in vogue in the day, the front hoop was a diminutive 16 incher, with a standard 17 inch wheel in the rear. Figure 95 HP pushing a 340 pound (dry) package; when the tach swings above 6,500 RPM, you’d better be holding on.

From the seller:
Suzuki RG500 GAMMA, mint condition.
With only 1060 Miles or 1700 KM and year production 1985, this is a very rare bike.
Complete JollyMoto Exhausts, make an astonishing sound.
Gsxr Wheels and front brake spacer to use original caliper.
Portuguese documents.
You can see by the photos, there in not even one single scratch or dent.
Original painting and decals all over the bike.
It has 2 keys.
Feel free to ask more pictures.
Bike is located in Portugal – Lisbon, but we work with Chas Mortimer Ltd to ship bikes to UK. You can also call them and ask for a feedback – shipping price is included.

This particular example has a popular mod that does away with the dreaded 16″ front rubber. It also sports some of the ultimate two-stroke pipe porn in the form of Jolly Moto chambers. Not only do the Jolly Motos weigh less than the stock pipes, they flow much better as well. That adds a power gain to the HP column, and an additional smile factor inside the helmet. They also make a fabulous sound at full song. The rest of the bike looks to be in pretty good condition overall (based on the photographs). Asking price is $32,500 US, with the seller open to offers. These are reasonably rare bikes that do not come up for sale all that often, although we do see Canadian bikes more frequently imported in the US. Given that this eclipses the 25 year mark for used bikes, importation into many States might be easier. Check out all of the details and photos here, and Good Luck!!

Nobody Puts Baby In a Corner: 1986 Suzuki RG500 Walter Wolf

Published March 23, 2022 by Mike

Of all of the fun, cool and very rare motorcycles we post here on RSBFS every day, few bikes get me as excited as a Walter Wolf edition of the mighty Suzuki RG500 Gamma. Festooned with the livery of Canadian businessman, motorsports enthusiast and general all around very rich guy, the Walter Wolf livery was available in both 250cc and 500cc Gamma variants, and was largely a cosmetic affair. Sporting what looks like black or dark blue – but in sunlight is actually a deep purple – the WW models came with livery-specific bodywork and instrumentation.

1986 Suzuki RG500 Walter Wolf for sale on eBay

The 500cc Gamma is no stranger to these pages, and enthusiasts everywhere have been viewing these brutal, square-four two strokes as road going GP bikes. In truth, these were more potent than the RZ500 competition, and sharper than most sport bikes of the era. They also held in reserve a lot of potential which could be coaxed out by clever and respected tuners, making them a bit of the holy grail for those seeking the combo of rarity, smokiness and outright speed.

From the seller:
Been sitting for years , ridden once and put into storage serious offers around $50.000, plastic needs repair , but not paint

To be honest, there is not much to go on with this one, but that doesn’t mean it’s not worth the effort. The seller claims it is in excellent shape, but also notes the plastics are in need of repair – but not paint. That could mean something non-visible, such as mounting tabs on the back being broken off (not uncommon). Zooming in on the photos show some minor scuff and wear, but I imagine this would clean up nicely. There appears to be a “ran when I parked it” vibe going on here, so it is not obvious if it currently runs. But if it’s been sitting I would recommend a leak down test to ensure the crank seals are still tight; nobody here wants to see this beauty seize. There is no detail in the ad on the total number of miles (kilometers) travelled, however a close up of the speedo shows 13,098 KMs, which equates to just over 8,100 US miles.

This is both an auction as well as a Buy It Now, however the starting bid and the BIN number are one and the same – just under $48k USD, or 60K in Canadian dollars. That is big money for a lot of (unclean) unknowns, but those unknowns need not be bad. There might be a real gem here – after all, it’s a freaking RG500 Walter Wolf Gamma! Check out all of the details here, and Good Luck!!

1990 Suzuki RGV250 SP2 For Sale!

Published December 2, 2021 by Doug

1990 Suzuki RGV250 SP2 For Sale on eBay!

I like to look at pictures. Do you like to look at pictures? Good- have a seat and feast your eyes on this 2 Stroke goodness.

From Mr Two Stroker
1990 Suzuki RGV250SP2. My rare RGV250SP2 which I have owed since March 1991 is up for sale from my collection. As the second owner I imported this bike from the original owner back in 1991 and therefore it’s not all corroded and oxidized like many Japanese imports of this age. For those who are no familiar with this rare SP2 model, it was only made by Suzuki in limited numbers for a few years. It’s a Japanese SP model bike with one big difference. The SP2 model came with the same gear ratios as the street non SP model. It did not have the tall SP racing transmission. But everything else was identical to the SP1 model, dry clutch, bigger carbs, and fully adjustable suspension, used on the SP1. I have spent a small fortune on upgrades for this bike. Many upgrades that are no longer available.

I totally rebuilt the engine less than 1,000 miles ago. New Pistons, rings, Crank seals, water pump, dry clutch upgrades, VHM O-ring high performance heads. The cylinders were ceramic recoated and lightly ported by my old friend Stan Stephens back in the UK. Ceramic coating is harder and more durable than Nikasil plating. Aftermarket billet power valves installed. It has the bigger SP carburetors on it with the Suzuki full SP jetting kit set up. Air box modifications. I put a UK made Pace high performance radiator on. This is a thicker high quality racing Rad. Not some cheap Chinese aftermarket product. That with silicone radiator hoses. Bike has a full power UK black box. All with a beautiful set of Lomas stainless steel pipes with carbon silencers.

For handling I installed a Tyga triple clamp, Sansei handle bars, racing 300mm Italian made front disk with 6 piston calibers, and 19mm front master cylinder. Brakes are phenomenal. Front suspension is fully adjustable and had been reworked by PPS. The back has a beautiful Penske fully adjustable rear shock, Wave rear disk. I just rebuilt the rear caliber, steel braided brake lines throughout. Installed, at a high price, custom made light weight magnesium rims front and back from Dymag. Tyga rear sets, steering damper, were added along with a new MPH speedo! It has almost unused Michelin Pilots tires on it, that are old and should be replaced.

I recently did a brake fluid flush, trans oil change, new coolant, new plugs, new battery, New petcock, Ultra sound carb cleaning. Bike was sitting in my collection and hasn’t been used in years.

Bike has a lot of titanium, stainless and aluminum nuts and bolts, Carbon front and rear fenders, Aluminum front fairing stay.

I have a Tyga unpainted rear tail section on it. Custom shock reservoir holder. The front fairing are the originals from 1990! They have some chips and minor cracks in them. Not the best of shape but still fine. Tank has a small ding in it that was there when I bought the bike in 1991. I was going to put a new Tyga front fairing on it. Have it all pained to look like a museum piece, but decided after 10’s of thousands of dollars, I’m not spending any more on I bike I no longer ride. It needs to go to someone who will appreciate and ride it.

This bike is ready fast with some of the best aftermarket parts that were available at that time. It’s ready to go and comes with a current valid California plate and title! I loved riding around on this bike, but after 31 years it’s another bike in my collection that I must sell. At my age, I’m getting to the point I’ll be hauling round on a motorized wheelchair rather than on a super-fast 250!!

I think I need a cigarette now, but I must confess- I usually look down my nose at heavily modified machines. However, not so much on this one. What’s different you ask? Lets start with the drool worthy Dymag wheels. Wooooo doggy!
How about we throw in a race worthy Penske shock, ceramic coated cylinders and full power chip? Had enough yet? Okay, it’s outfitted with some tasty TYGA carbon and aerospace grade aluminum bits and bobs too.

These make around 60hp, but the power band to make that power resides in a pretty narrow stretch of RPM’s. Usually, hitting between the 8-11,000 range for peak power. I bet those Lomas Shotgun’s scream “FU!” when you get on the pipe 🙂

Let’s look at some more pics shall we? Thank you! I don’t mind if I do.

Clean, tastefully modified, well sorted, definitely rare and most certainly one of a kind!

Step right up and don’t be shy (The Tubes 82′) –

Check out this 1990 Suzuki RGV250SP2 here!

Cheers!

Freaky Friday Bag-O-Bikes feat. Bimota, Guzzi and an AMAZING RG500!

Published August 27, 2021 by Doug

Moto Guzzi Daytona For Sale on Craigslist!

Big, Beautiful, and Body Positive- I’d ride it!
Even though Guzzi describes it as a “sport bike” this, 450#, shaft driven machine pales in comparison to today’s 200hp rockets, but it does have a certain mystique about it. I bet with a set of pipes the 992cc V2 would belt out a musical note worthy of the top spot on Mikes Mix-Tape. The reach from the seat to the clip-ons looks to be a bit long- can anyone confirm this?

1993 Moto Guzzi Daytona 1000
Fully stock.
Beautiful bike.
Always garage kept.
Biposto version (very rare)
#2 of only 250 that were imported into the US — own a piece of motorcycle history.

2007 Bimota DB6 Delirio For Sale on Craigslist!

Simply a work of Hyper Bike Art. The Italians know what I like and continue to build some of the most eye pleasing machines- I could sit and look at this one All. Day. Long.

01 of 23 built in the world.
Power is from a Ducati 992cc SOHC L-twin paired with a six-speed transmission, and the bike is finished in Red/white with carbon fiber fenders and engine covers.

Additional features include Brembo radial front disc brakes with wave rotors, Zard mufflers, a steering damper, an inverted Marzocchi fork, and seating for two.

1989 Honda Hawk in Grey For Sale on Craigslist!

I had one of these gems on last weeks B-O-B’s post and as long as I keep finding them you’re going to keep seeing them 🙂
Super cool bikes that never gained much traction as a street machine, but they have plenty of cult following on the track. Back in the day, I had the opportunity to purchase one of these, but at the time I was all in on FZR400’s. Much older and wiser now, I kick myself for not buying it when I had the chance.

Rides great no funny noises or smells, no overheating problems, battery is new , good chain & sprockets, good brakes, good tires, original paint, no accidents, just in great shape, no oil leaks it’s a Honda.

It’s a Honda- Preach it Brother!

Capirossi Ducati Monster on the cheap!

Nothing too crazy here other than some snazzy decals. However, $4,000 for a 2,000 mile Ducati seems like a pretty good deal to me, but apparently, I’m an outlier because this one has been sitting on CL for a while.

Showroom condition on this Capirossi Monster. Only 65 of these were shipped to the USA.

1990 Honda CB-1 For Sale on Craigslist!

Another small Honda that didn’t garner too much attention when it was released, but I have to tell you- these are some neat little bikes. This 400cc inline four has gear driven cams and a 13,500 screaming red line. You don’t see these very often and when you do, they’re usually all jacked up with nasty paint, bumps and bruises. This one “appears” to be pretty nice and would make a great grocery getter or commuter.
What do you all think about these?

1990 Honda CB-1, 6 speed, 25,500 miles. Rare bike: 400cc inline four with gear driven cams, revs to 13.5k RPM. 3rd owner (all were in Bay Area), parked in garages its whole life. Under 300 miles on Pirelli Sport Demon tires. Original paint and seat.

1972 Laverda 750 SF1 – Italian Cafe Racer For Sale on Craigslist!

These older “Cafe Racer” machines always make me smile and while it would be a bad move on my part; if I owned this I’d wear a leather helmet and smoke goggles while riding it. You know- for the nostalgic kool factor.

Sensational Bike, Very Low Original Miles … Rare, Cool and Fun to Ride

1985 Suzuki RG500 Gamma w/ only 864 miles- For Sale on Craigslist!

Last night, I was kicking it and lounging around, sipping on a cold snack with some time to kill. The normal hot-bed of rare sport bike supply was a little slow so, I stretched my short legs and ventured out on the dark world wide web in search of some tasty eye candy for all our highly regarded followers. I have to admit, I didn’t have high expectations, but my dung luck would prove me wrong once again.

Grab your favorite sudsy beverage and feast your eyes on the gems I found.
