T.M. Designworks, the inventors of the strongest raw chain there is. Indestructible.

The raw PRO chain is made from a single piece of teflon and unlike the standard model has the interchangeable chain skate.

The only after-market product to be for 2 consecutive years (2004 and 2005) the best product according to Dirt Bike magazine.

This cruna obtained its patent in 2006 for the solid teflon structure of the cruna itself.

Don't be fooled by appearances: the light, clean shape actually hides a much more durable structure than the standard that doesn't reduce performance.

This product uses a special plastic that gives a higher force.

The patented TMD memory system keeps chain guidance in line even after a strong impact.

The black color allows you to use a higher UV content and more lubricant that is not available in standard crunes and no other cruna on the market.

This guide is the highlight in which champions of the level of Barry Hawk, Ty Davis, Russ-David Peason, Randy Hawkins, Paul Krause or belonging to team Suzuki off road, Kawasaki off & Honda off road are strongly believed
