Dumonde TECH
Kart Racing Lubricants -- Castor and Synthetic 2-stroke oils, Chain Lube, Gear Oil, and More.
One of the world leaders in kart racing lubricants, Dumonde Tech Racing Oils was started as a kart lubricant company and has since expanded into other motorsports and bike racing. Based here in the Northwest, Dumonde Tech's first product was a high temp clutch oil for road racing karts, in 1985. Since that time, through years of extensive research & development in the lab and real-world conditions, Dumonde Tech now produces some of the most advanced lubricants available for racing. Longevity, protection, and outright speed.
Micro Resistant Complex Compound© (MRCC) technology provides premium lubrication by reducing friction better than traditional lubricants. The increase in adhesion creates higher film strength reduces coefficient of friction.
BHP Drive Chain Oil - Internationally recognized complex compound prevents horsepower loss through chain drive systems.
Dumonde Tech BHP chain lube penetrates by migration and plates all surfaces. This unique formation substantially reduces friction. BHP's liquid formula penetrates chain links & rollers and the coating turns to an extremely low coefficient plastic polymer. The polymer impregnates all pores, protecting the chain against rust and corrosion while providing superior lubricating properties. BHP also contains O-ring conditioners. BHP is the best chain lube for race karts (as well as motorcycles, micro & mini sprint, and ATV's).

Dumonde Tech Racing Castor - 2-Cycle Pre-mix Castor
Dumonde Tech Racing Castor is a modern version of a traditional proven castor. A blend of the purest de-gummed ricinus castor and performance additives. Dumonde Tech Racing Castor is a demiurgic castor formula. It is technologically designed to provide superior lubrication for two-cycle racing engines, and it does so with less carbon build up. Dumonde Racing Castor burns cleaner then other full castor oils. Excellent for high temperatures and high rpm.
