Yeah, frees up some power, but only when you're at max-throttle would the extra power make a difference (otherwise on street bike, you can just open throttle more). Weight savings of a couple pounds also really only affects a race-bike.

All the guys I've talked to on track says their 415 lasts about 1-season before needing replacement. That's with regular cleaning and oiling, but the average load is much, much higher than a street-bike.

I prefer my 428 conversion with X-ring chain. Almost as much weight-savings as 415, but lasts much, much longer. Longer than stock even.
