So with alot of modifications it can do 187mph, a standard busa with limiter will comfortably do 186mph take the limiter off and standard a gen 2 will do 196mph with a few modifications 200+
When I had the dyno session it span the dyno at top speed of 218mph the guy doing the dyno commented that with the torque curve of my bike being so linear without any dips and bumps he said it must have had some money spent on it and that 218 on the dyno is a realistic on road speed of 207/8 mph flat out with wind resistance
