1982 Suzuki RGB500 MK7 Grand Prix Factory racer on ebay

1982/83 Suzuki Gamma XR40 RG(B)500 MK7 Factory Grand Prix racer listed on ebay with a $60,000.00 B.I.N. and a current bid of $30,000.00.

This is a chance of a lifetime to own a true Grand Prix factory race machine. You are reading correctly; a true Suzuki Factory Grand Prix racer can be had for your personal collection or a vintage day at the track. Yes, I would have to give it a go at least once and maybe twice if it was really fun.

The exact history is a little vague at the time of post, but it appears to be a 1982 model that was purchased from the factory in 1983 by a satellite Grand Prix team. This particular machine has had a frame up restoration and in my opinion looks extremely nice. The current paint scheme was copied from the 1982 Randy Mamola HB Suzuki racer. Below you can see the two and I think you’ll agree it looks extremely good when compared to the original factory bike. I noticed a few mechanical differences between the two, but somethings just aren’t obtainable 27 years after only producing a handful of race bikes. It does appear that the seller did a nice job of maintaining the integrity of what would have been original to the factory race package.

Something interesting to point out about the history of this bike is that it was raced in the 1988 & 1989 USGP by Eugene Brown, of Portland, Oregon. I spent a considerable amount of time researching the 88/89 USGP and there were several Suzuki’s on the grid, but I couldn’t find a site that stated what generation of RG had been entered in the race. No matter how you slice it, history or no history this a factory Suzuki Grand Prix machine and you have an opportunity to park it in your showroom. Take a look at the documented rebuild pictures and judge for yourself.

Quote from the lising:

This is one of the limited production GP bikes available to the private teams and the first year to use the works stepped square 4 cylinder arrangement and the all new full float rear suspension and the front fork anti-dive system.

For 1981 and 1982 the Suzuki`s were the bikes to have and in 1981 Marco Lucchinelli won the world title on the Works RG Gamma XR35, followed by Franco Uncini in 82 on the Works RG Gamma XR40.

I’ve spent several hours watching old Grand Prix video’s from this era and I always leave shaking my head and saying “WOW, those were real men”. I can only begin to imagine what it must have been like to ride a 170hp machine that weighed only 292lbs. So, I’ve attached a video of Randy Mamola trying to tame an ill handling 500cc 2-stroke and it is truly an amazing sight – only to see him get flicked off like a………..a……well a cowboy in a rodeo.

The seller is also including a huge and quite expensive spares package that I’m going to assume will be needed to keep a bike of this nature in pristine running order. Here’s what you’ll get if you pick this one up.

The spares package is said to be worth $10,000.00 and by the looks of it, I wouldn’t disagree one bit. This is an opportunity of a lifetime and available for the taking if you have an extra $60k burning a hole in your pocket.

I came across another video that really has nothing to do with this bike other than there’s a distant connection via Randy Mamola. Check it out and then watch it a few more times just as I did.

Cheers!
