The seller calls this the “YamaGamma”, as it combines a Suzuki RG250 frame with a Yamaha RZ350 engine. What do you think about this interesting combo?
Never sold in the US, the Suzuki RG250 Gamma was introduced in 1983 as the first mass-produced motorcycle with a 100% aluminium box section chassis. This, combined with the light weight of <300 pounds, anti-dive forks, and "Full Floater" rear suspension, is why it is considered by some to be the first street-legal race replica. The original Suzuki 250 motor was good for 45 horsepower, but Yamaha's RZ350 engine was rated for 59!
The seller of this example (VIN: GJ21B121220) says that the RZ350 engine fits “with a simple engine spacer kit from the U.K.” and “the rest is just fitting the RZ wiring harness, electrics and a few other bits.” Confusingly, he/she provided the above photo of what I presumed were both bikes involved in this project, but they note that the frame was a Walter Wolf Gamma (which does not feature the blue/white livery). The seller had the bike painted and wheels powdercoated It’s set up with GP shift and everything is said to work but the oil injection pump (still on the bike) has been disconnected so it currently runs premix. The only other exception is the tachometer, which is not hooked up.
