Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

About this product
Front wheel reinforcement rings for PROMOTO-MX chassis
This aftermarket reinforcement ring set is engineered to strengthen the front wheel mounting interface on compatible PROMOTO-MX motorcycle RTR models. Machined from Aluminium 7075, the rings provide a harder, broader contact surface at the wheel face to reduce localized wear and help retain alignment under repeated loads.
Installation uses the supplied Grade 12.9 fasteners and replaces the original thin contact surfaces with a thicker bearing face for the wheel. The upgrade is intended for hobbyists seeking improved rim support, reduced deformation and predictable steering characteristics when setting up LOSI PROMOTO-MX machines.
Packing includes
- Front Wheel Reinforcement Rings set – 2pcs
- Grade 12.9 black Flat Head Screws 2.5×25 – 12pcs
Compatible Models
- LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06000
- LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06002
Apply these rings as a precision upgrade to preserve front wheel geometry and extend the service life of wheel mounting areas on the specified PROMOTO-MX RTR units.
What hardware is supplied with the rings?
The package includes two reinforcement rings and twelve Grade 12.9 black flat head screws 2.5×25, which are used to secure the rings in place.
How do these rings alter the load path?
By increasing the contact surface area at the wheel face, the rings distribute load over a thicker bearing interface, reducing stress concentration and limiting deformation at the rim mounting points.
Are any modifications required for fitment?
No permanent modifications are required; the rings replace the factory contact surfaces and use the supplied fasteners for direct installation on the listed PROMOTO-MX models.
Recommended inspection after installation?
Check screw torque after initial use and inspect mating faces periodically for wear. The 7075 material improves longevity but routine checks ensure continued fit and performance. Write Product Review Please sign in your account before you can write any review.
