With Yoshimura's involvement in the Suzuki race team, the RM-Z250 receives a ton of Dyno time. The results are obvious. Tons of usable over-rev let you hold the throttle on long enough to pass that guy in front of you instead of having to shift. Coming out of corners, the increase in mid-range is huge. These cams make the RM-Z250 pull like a tractor. This is a big increase in power and it's all right where you need it!
* Cam timing should be set by a certified mechanic to ensure proper function. Improper installation or cam timing could result in catastrophic engine failure.
