Grant31781 Posted June 10, 2019 Share Posted June 10, 2019 I thought this was a neat video. A bit of reckless riding. 1 Link to comment Share on other sites More sharing options...

Grant31781 Posted June 10, 2019 Author Share Posted June 10, 2019 I was really impressed that a 155cc bike could run that fast! Link to comment Share on other sites More sharing options...

My old Yamaha DT 100 would hit 65 mph. Still, would make someone a great city bike. I like it's looks. Beemer Link to comment Share on other sites More sharing options...

My old 200cc 4 stroke dual sport would run 60 wide open on flat ground. Also think of the 125cc Grom. It is slow!

Maybe a 2-stroke is a little quicker to get up to speed but the Honda XL100's top end was right about the same as my Yamaha DT 100. I guess we can agree the MT 15 isn't fast but who would expect it to be? Beemer Link to comment Share on other sites More sharing options...
Grant31781 Posted June 10, 2019 Author Share Posted June 10, 2019 Gearing has a lot to do with the top end speed. In general 2 strokes make more power per cc than 4 strokes do. If you have a 250cc 2 stroke and a 250cc 4 stroke. The 2 stroke will make more power. YZ 250 2 stroke 48.8hp at 8,800 rpm YZ250F four stroke 33 horsepower old version 41.76 horsepower from the 2019 YZ250F at 12,900 rpm I would not call that equal. The MT15 was faster than I expected. Little booger looks so fun. 1 Link to comment Share on other sites More sharing options...
