Watch out yamaha. Honda is probley going to come out with their Ti valved bike next year. Honda is always a copying off of other companies. If they are not it's a terrible idea any way. Yamaha is an innovator. enough said

This article seems kinda vague. If the valves are that much lighter, did they change the valve springs?? Would they not be able to change the cam a bit to capitalize on less valvetrain friction?



As far as feeling the difference of the Ti vavles it seems more like you could feel the carb differences.

I would rather see yamaha sell their 2 wheel drive racing dirtbikes. Can't remeber what race, possibly dakar, but the bikes give tons more grip in sand/really lose dirt. Now THAT would be innovative for a production bike.

How much for a valve replacement? (When/If it finally goes...)

Well, actually energy = mass times the square of velocity, not mass times acceleration. You got the general idea right, though. Half credit.

If you want a desert bike, I would recommend the 426, as it is more powerful, faster (If I recall correctly) and a little more heavy than the 250. For desert racing, I would prefer the heavier bike, as it is less likely to be blown around @ high speeds, and the power is more tractable.

For all day trail riding...I wouldn't recommend this bike. The seat is as hard as hell....permanent wedgy is a definite possibility (ha, ha). But seriously, the power is awesome, almost two strokish, in nature....but if you are also looking for comfort, or are riding in technical terrain....this bike wouldn't be the best choice....How about an XR 600?
