Evr

The Sestamarcia EVR collection currently includes a slipper clutch for selected Honda CRF 450R applications. The page is therefore focused on the product actually available rather than extending the description to EVR ranges that are not present in the catalogue.

EVR slipper clutch for Honda CRF 450R

A slipper clutch is designed to manage reverse torque from the engine during aggressive downshifts, helping make rear-wheel behaviour more controllable during deceleration.

The benefit depends on correct installation, motorcycle setup and intended use. It does not directly increase engine power.

Model- and year-specific fitment

The EVR product available from Sestamarcia is associated with Honda CRF 450R models for selected years. Before purchasing, always verify the model, year, version, product code and original clutch configuration.

Installation and configuration

A complete clutch system includes the basket, plates, hub, pressure plate, springs and other parts. Installation must follow the specifications of the kit and motorcycle.

For racing clutch work, installation by personnel experienced with the specific model is recommended.
