“At 178 mph and 11,000 rpm an engine failure can be disastrous. That’s why I count on a copper-core Derale Competition Oil Cooler. In testing supervised by technicians from a major oil company, oil temperature in my Formula One Suzuki reached 180° with a Derate Competition Oil Cooler installed. At identical lap times and ambient temperature, but without the Derate cooler, oil temperature reached 230°.
“That’s a 50° difference. Just as important, Derale coolers are reliable. I can’t afford to have oil spraying all over my tires at the kind of speeds my bike reaches. Last year I ran the same Derale Competition Oil Cooler in five endurance races without any leaks or failures.

Buy Reliable Cooling. Buy Derale.
In a test on a stock CB750F street bike, a Derale Street Oil Cooler outcooled an equivalent Lockhart cooler at 60 mph. Derale dropped oil temperature from 217° to 179°F, a total of 38°. Lockhart dropped oil temperature from 217° to 205°F, a total of 12°. And Derale’s complete street kits cost only $94.50, an amazing $60 less than the closest competitor.
