CR 750 Honda

Honda built the CR750 to race at Daytona in 1970. The real racing however was done by legions of Honda riders all over the world who raced kitted CB750 Fours against the best of the rest. Honda sold a limited number of CR kits for the Honda CB750 for US$10,000 which made them somewhat exclusive considering CB750s could be bought for not much more than a grand at the time. The kit consisted of a race camshaft, stronger valve springs, oversize inlet valves and smaller exhaust valves, 2 ring 10.5:1 slipper pistons (standard is 3 ring 9:1), a close ratio gearbox and battery-less ignition fixed at 35 degrees advance.

Also included were four open megaphones, rear sets, racing seat, petrol tank, aluminium oil tank, fairing, twin disks up front and a giant 240mm 2 leading shoe drum brake up back.
Special camchains and primary chains were also supplied but this did not prevent lots of cam chain failures during races.

The standard frame was used contributing to a quite hefty racing weight of 385lbs. Using 31mm racing Keihin carbs the CR750 produced a healthy 90ps at 9,700 rpm making it the most pwerful race bike in its class.
