There will be very, very little top speed difference between the 2 stroke and 4 stroke of the same HP. Same applies between manufactures for their respective models. The 2 stroke may have a little edge in the acceleration department, but that's also debatable.
Would you agree then that it's an old wives tale that 2 strokes are always faster than 4 strokes??? That's all I hear about and I've never really been able to make a comparison myself.
Always faster? Can't really say if 2 strokes are always faster. Depends on who you talk to or what magazine motor tests you read. But on a toon, the difference will certainly be negligible for a given HP..
