DESCRIPTION
T4+ offers up to 2% more power over T4, and better throttle response across the entire RPM range. T4+ is designed for stock or modified 4-stroke engines. Unleaded and ethanol-free, T4+ is a direct pour-in replacement for premium pump gas, preventing common damage caused by ethanol-based fuels. While riders facing extreme conditions are forced to add octane boosters or race fuel to increase the octane of pump gas, T4+’s 98 octane rating (R+M/2) provides greater protection against detonation.
