Description

Fully refresh your Yamaha YXZ1000R’s top end with the REV6 Master Top End Refresh Kit, built for 2020–2025 models. This kit not only restores compression but also replaces wear items in one go. Because it covers pistons, valves, and sealing parts, you’ll avoid sourcing multiple kits.

Every component is built to match OEM tolerances and inspected before shipping. As a result, your installation will go smoother and performance will hold up over time. The kit ships nationwide and comes with a 1-year warranty. You can also upgrade to a 2-year no-fault option for extra coverage. With years of experience in Powersports engine builds, REV6 ensures long-term durability in every part.
