Looks nice but it kind of takes away from the point of the TTR250. The TTR250 was a mild bike that was good for begginers, easy to work on, hardly had to work on, and was bullet proof. The WR mat be lighter, faster, but the power made might not be very good for a begginer rider. Also, the WR requires alot more work to be done. But it would still be nice to have.
Actually, the articles I have read say that the motor is a DOHC four valve design in an aluminum frame, but the engine and frame are not the same as the American WR250F off-road racing bike. It is probably designed to be more durable like the previous TTR250. We have a 2001 TTR250 and really like it, this new one looks to be a good upgrade, especially if it's lighter. Dirt Rider magazine also said it might have EFI.
Pred - Here is a better version of that concept for his next bike. ;) The Scorpa T-Ride - E-strart Yamaha 250F engine in a chassis that is half trials bike, half enduro, and the best part they are claiming 190 lbs. :cool:
