Description

If you're running a TTR125E in competitive or high-performance riding conditions, factory cam timing limits your acceleration and throttle responsiveness. The Hot Cams Stage 1 transforms low-end power delivery with optimized valve lift and duration, giving you the edge off the line without sacrificing reliability. This is a bolt-on upgrade that works within your existing valve spring package—no machine work required.

Stage 1 tuning prioritizes the torque curve where it matters most on a 125cc platform: immediate spool-up and mid-range grunt. Whether you're racing tight motocross tracks or pushing a trail bike to its limits, sharper throttle response and earlier power arrival translate to faster lap times and better control in technical sections.

Helps keep cool, works great!
