Let me say that the new Yfz 450r looks bad ass :thumb:
Another great Yamaha product!!!
This is a bone stock run...run file 2 vs air lid removed run file 3 vs air lid and sparky removed run file 4.....redline seems to be set @ 10 k
For the guys wanting to know if it is safe to rund without lid and sparky id say GO AHEAD!!! the top end is still rich and has more there with the proper tuning<<<<NEED PC5>>>>>>
