Optimize the transmission of your gearbox with theNu Z13 Primary Treespecially designed for competition karting engines TM RACING (versions R1, R2 and R3).

Central and critical component of transmission, this tree collects the torsion and extremely violent load forces characteristic of gearing-box karting engines. Proposed here in naked version with a profile of 13 teeth (Z13)It guarantees maximum mingling accuracy and outstanding reliability in competition.

The 2nd speed gear z16 is a high precision piece for the primary shaft of gear motors TMKART R1 and R2. This pinion is designed to support significant mechanical shocks during ultra-fast reports in competition.

• Number of teeth (Z16): With its 16 teeth, it defines the specific demultiplication ratio of the second speed to optimize the tight turn output restart.

• Treated steel: Made in a special high-strength steel with thermal surface treatment to limit tear from teeth and crabts.

• R-Series reliability: Developed specifically for the architecture of the motors R1 and R2, guaranteeing a perfect alignment on the primary shaft.
