Recommended Posts

I think it depends on the rider...

A guy got on here months ago, had dyno tuned both an 85 and a 150. Says the 85 had 0.5-1 more hp than the 150R. So judging from that, you gotta figure the 100 would have more than the 150R.

Getting the power down to the ground is another story.

Most average riders can make a 150R go faster than if they were on a 2-stroke. The 4-stroke takes less effort to ride.

The 150 is a little faster...2 mph on the dyno.

Do you have a dyno chart for the 150r you can share?

you can't say one is faster than the other one because there's just to many things that make one faster bye a little bit so it's all the rider pretty much.
