I think that price is nice. But kit parts for $300 (market price) is 'my wish'. I guess need much much soooo much more number of order for make it happen with that kinda price. And this parts can't compromise about quality. I am throwing small piece of rock here right now for try to make mud slide.
Dream is dream, idea is idea. Should we request to Yamaha for sale this bike? It's nice to have more choice but how much you pay for whole bike? So, I think tune up kit is no bad idea for TW/TTR enthusiast.
Stock motor is best toughness motor for sure. I want to hear more member's voice.
