We love what See See, Speed Merchant and Suicide Machine Co have done with the Street 750, and this 'factory' racer has the looks to replace the XR750.
The XR750 is still winning half-mile races, with Mees on board, and pushing for wins with other riders including Coolbeth, but the Baker's factory XR keeps breaking, perhaps because it's at the very limit of what is possible, as tuners chase more power by increasing rpm limits. The 4v per cylinder, liquid-cooled XG will be able to rev much higher, more safely than the air-cooled 2v XR750, a bike engine that debuted 42 years ago.
This is going to be a fascinating new chapter in the sport's history. G
