the 426's do smash gearboxes occasionally, especially if used for a lot of bitumen work. Not sure if the 450's are any better, time will tell. At the end of the day, they are a race bike with lights. There will always be comprimises.

The 450's do have some problems, but not as many as the 426. 3rd, and 5th gear like to go out. I just did a rebuild on a 01' 426 last week as a matter of fact. The reason for these going out is the shift forks are on a pin that slides into the cases when you shift. If you shift it hard without the clutch those pins will miss the hole, and bend the shift fork. It then causes the "dog ears" as they call it to get rounded over. There for you have to buy a shift fork now, and 2 gears.
