I bought a TYZ and after riding a Sherco 290, it seems like the way I remember the air cooled but a bit better, for club trials it's probably more forgiving and yes it is heavier, but things happen a lot slower, as for the Scorpa TYZ debate, The TYZ just seems to do what it says on the tin, Just don't drop it off a waterfall, But I assume the scorpa is the same in a lot of respects, and also has the bonus of next to zero depreciation
