Description
A worn or slipping drive belt robs your Indy 650 of acceleration and responsiveness—and forces your engine to work harder, generating heat that degrades performance. The Ultimax Pro 138-4716U4 restores that critical power transfer with a thicker cross-section and engineered cog geometry that grips without slipping, while its heat-dissipation design keeps operating temperatures down for longer belt life and consistent performance across extended riding sessions.
This is a direct-fit, bolt-on replacement for 1988–1992 Polaris Indy 650 models. Installation is straightforward and requires no fabrication or professional assistance.
