Description
xV-Twin Transmission Oil for Optimal Gear Performance
Maxima V-Twin Heavy-Duty Transmission & Gear Oil is a mineral-based lubricant designed for 4-, 5-, and 6-speed gearboxes in high-performance motorcycles. It provides a robust protective film that guards gears during torque peaks and rapid shifts, making it a thoughtful choice for Harley-Davidson and other V-Twin machines without wet-clutches.
The formulation aims to minimize wear and surface damage while withstanding the heat produced by spirited riding. A shear-stable base helps preserve viscosity, supporting consistent shifts as you push for peak RPM and when the terrain demands quick gear engagement.
Key benefits at a glance
- Strong film strength to guard gears during shock loads and high RPMs
- Wear, pitting, and spalling protection for long gearbox life
