Yamaha YZ65 Extended Swingarm
YZ65 Extended Billet Swingarm – All Years
Big Builds. Tuned for Faster Kids.
The Krooztune 30mm Extended Billet Swingarm isn’t just an upgrade — it’s a key piece in building a full-spec YZ65 weapon. Designed for serious racers and parents crafting the ultimate “big 65” setup, this isn’t your average bolt-on part. It’s engineered for custom builds chasing holeshots, top speed, and stability with size near halfway to an 85cc chassis when matched to fork raising components.
This swingarm is CNC-machined from billet alloy, it offers uncompromising strength, rigidity, and weight savings — built to handle aggressive riding and race-level abuse. The extended length and raised rear ride height give your build a taller, more stable stance, especially when paired and balanced out with our Fork Extension Kit and upcoming Billet Axle Lugs.
Key Features:
-
30mm Extended Length – Designed for full-size custom 65 builds, not stock geometry. Big Boy 65 cc setups, flat track racing or custom builds.
-
Raised Ride Height – Taller stance pairs perfectly with fork mods and longer shock options
-
Billet Alloy Construction – Lightweight, strong, and precision-built for racing
-
Machined Lower Shock Mount – Threaded design like KTM/WP for a secure, race-spec fit. Bolt supplied to suit
-
Clean Shock Bolt Fitment – No nut required — threads directly into the swingarm
-
Part of a Bigger Setup – Ideal for custom height builds with extended forks and future upgrades
If you’re pushing the limits of a YZ65 and building something beyond OEM — this is your swingarm. We have built many bikes instore that are halfway point from 65-85cc racing now all over the world.
