💥 Beta 350RX 2T 2026-on TSP Power kit Announcement! 💥
Our Beta 350RX package delivers major performance gains across the whole RPM range, with a massive 8HP over the standard peak power! This is an incredible 16.5% increase at peak power, absolutely transforming the power over the stock engine setup! This bike now performs how we believe it should have from the factory.
This result is achieved by running the following products:
- TSP Cylinder head & Insert with a 1.5mm thick base-gasket to suit
- TSP Base-line jetting specifications
- TSP Recommended Power-valve settings
- Optional: TSP offset flywheel key
Instructions on how to set up the powervalve actuator arm to suit the raised cylinder setup will be included.
This setup will also improve the throttle response/smoothness, with reduced risk of detonation.
