Delivering a claimed 145 crankshaft horsepower at 15,400 rpm, the highly tuned R6 engine utilizes Grossewächter camshafts, a slightly higher compression ratio, ported and flowed cylinder head with race kit single valve springs and valves/valve seats reshaped to work with the revised porting. The variable length intake system also has options for trumpet length in 10mm increments from 30mm to 70mm, with the actuation point also adjustable via the MoTeC ECU.
