Build Core Engine – Important Details

This listing is for a Build Core Engine. It is not a ready-to-install motor. We require a complete, rebuildable core to remanufacture. For this reason, the core must be intact, free from major cracks, and without missing parts.

Because of this, we recommend reviewing our Help Center before purchase. There, you’ll find details on core acceptance and shipping instructions.

Warranty Protection

REV6 backs every engine with trusted coverage:

• 1-Year Warranty Included – Standard protection with every build
• 2-Year No-Fault Warranty Option – Add for $450 and receive complete replacement coverage

In addition, you can view full terms anytime in our warranty policy.

Our technicians assemble each engine, and another expert inspects it before shipping. In fact, this double-check process ensures accuracy and reliability. With over 50 years of combined powersports experience, the REV6 team delivers engines that exceed OEM standards. Therefore, you can trust your 255XD to run strong for years to come.
