It is a trials bike, so loads and loads of power on the bottom, and lots of flywheel.
Not much HP and not fast. Although 5th and 6th gears are pretty high so will easly do 60mph.
I weighed it and it is 75lbs lighter than my old KTM 300 XCW (both about 3/4 tank fuel)
Like night and day.
For super tight, nasty trails, especially with a lot of obstacles, it is fantastic!
I used to have a 450 EXC, and the 300 felt WAY lighter.
I also had a 640E KTM- the 450 felt (and was) way, way lighter.
The 300 felt way lighter than the 450
The difference between the 300 and the OSSA is more than the difference between the 640 and 300.
Huge.
Here is a video sample.
