The RTE Full Mod 30.5cc engine is all new for 2025.
This engine has fully modified crankcases set up perfectly, all end float is set via bearing shims, not crank shims, and case porting is now completed in a mill, and finished match porting by hand. Beautifully hand-ported cylinder with Rooster Tails new special combustion chamber and new short spark plug (CMR7A). Also a milled, modified and lightened piston that reduces friction and maintains compression at high rpm. How can you beat that?
Also included is our new RTE Full Mod Crankshaft Seal Arrangement. We have designed a new seal to stop vacuum leaks which cause dust ingression, destroys engine bearings, cylinder plating, piston rings and tune accuracy. Our new seal arrangement provides a very long life and a higher quality tune stability at all temperatures.
This combination produces huge increases of power everywhere and an even larger increase of torque, while still retaining the ability to rev really high.
If you can handle it, and you want to be out in front, you'll need the 30.5cc from Rooster Tail Engines.
