UMA RACING AEROX ROLLERS

Fitment & Size

• Designed for Aerox 155 (also compatible with NMAX, NVX) according to listing. 

• Roller dimensions: 20 × 12 mm (diameter × width). 

Weights Available

• UMA offers a range of gram weights: 9 g, 10 g, 

Material & Build Quality

• Self-lubricating plastic material — helps reduce internal friction. 

• Heat-resistant and wear-resistant, suitable for high-RPM use. Weight precision is maintained to ensure consistent CVT behavior.Performance Characteristics

• Lighter Rollers (9 g) → more aggressive acceleration, but require higher RPM to reach top ratio.

Durability

• Built to withstand repeated rolling inside the variator / pulley, even under high load.

• The material choice (plastic + self-lubrication) ensures a good lifespan when used properly.

Tuning Compatibility

• These rollers are commonly used in CVT tuning for Aerox. You can mix weights or try different grams to tune performance for your riding style (city, uphill, highway). 

• When paired with a pulley kit (like the UMA Racing pulley drive face), different roller weights can significantly affect acceleration and top speed
