T.M. Designworks Drive Chain Guide

The Gold Standard in Dirt Bike Chain Guides

When it comes to drive chain guides, few names carry more weight in the off-road world than T.M. Designworks. Based in Oregon and manufacturing in the USA for over 30 years, T.M. Designworks is widely recognized as the worldwide leader in Chain Slide-N-Guide technology — and their rear chain guide lineup is the product that built that reputation.

Patented Technology That Protects Your Drivetrain

What separates T.M. Designworks chain guides from the competition starts at the material level. Their guides are built with a proprietary Return Memory System (RMS) plastic formula — an industry-leading compound that absorbs impacts and returns to its original shape, rather than cracking or deforming under trail abuse. Oil additives are injected directly into the plastic to reduce rolling resistance, while 100% UV protection keeps the guides from fading or becoming brittle over time. These are not cosmetic details; they are engineered features that directly extend the life of both the guide and your chain.

T.M. Designworks also holds US and EU patents on their chain guide designs (US Patent: D794,512 / EU Patent: 002583716-0001), underscoring the genuine innovation behind these parts. Every guide ships with all necessary mounting hardware included.

The Factory Edition Chain Guide Series

T.M. Designworks offers three distinct rear chain guide options in their Factory Edition series, each tuned for a specific riding discipline:

• Factory Edition SX – A compact, slim solid-body guide developed specifically for Supercross and Motocross track riding. Lighter than stock, with a replaceable wear pad and compatibility with most standard and narrow sealed chains. Ideal for riders who want to shed grams without sacrificing protection.
• Factory Edition #1 – A versatile guide built around the same "Zero Chain Drag" plastic philosophy, delivering smooth performance and consistent chain tension across a range of riding conditions.
• Factory Edition #2 – Designed with an open body construction that is stronger than even solid-bodied guides, while allowing sand and dirt to fall away from the chain rather than accumulate. The replaceable rub block uses T.M. Designworks' proven Zero Chain Drag plastic and is field-replaceable for maximum long-term value.

Proven at the Highest Level

These aren't just aftermarket upgrades — T.M. Designworks chain guides are trusted by championship-winning race teams worldwide, including Factory KTM and Husqvarna Off-Road operations. The guides have been recommended by MXA, Dirt Bike, and Dirt Rider magazines, and independent long-term testing has recorded over 500 hours of rear guide life with wear pads still intact. That kind of real-world durability speaks louder than any spec sheet.

Whether you're lining up on a supercross track or hammering through rocky enduro terrain, T.M. Designworks rear chain guides are engineered to keep your drivetrain protected, your chain properly tensioned, and your momentum uninterrupted. Browse the full selection of T.M.
