It would need to be a full custom job for your frame, as it was for mine. Most of the clowns selling these wouldnt even know that they need a different pipe. The YX 150 makes it power too late in the rev range and I like the kitted 125 Jailings better especially for the track. If you want a 150 get a second bike. They are better suited to open tracks and trails I think. The track we ride on its bloody hard work trying to keep the 150 in the zone. You rode mine before we finished the motor. Now making similar power to the yx but shit loads of balls down low and does the YX150 on our track. Would be different story on a longer more open big bike style track.
