This aftermarket set is made to reinforce the front wheel assembly on compatible PROMOTO-MX motorcycle RTRs. Machined from Aluminum 7075, the rings improve resistance to wear where the wheel face contacts mounting hardware, helping to maintain alignment during repeated impacts and rough runs.
They install using the supplied hardware and replace thinner factory contact surfaces with a broader bearing face for the wheel. Use these rings to reduce rim flex, limit deformation and secure steadier steering response while tuning LOSI PROMOTO-MX bikes.
Fit these as a focused upgrade to help preserve front wheel geometry and extend the life of rim mounting areas on the stated PROMOTO-MX RTR models.
