About Us

Watt-man.com started in 2005 with the development of the Thermo-Bob, a cooling system modification
to extend the life of the Kawasaki KLR650. We’ve grown into supporting the snowbike market as well, with an assortment of Thermo-Bobs and Engine Jackets to maintain engine temperatures and extend
engine life.

 

What is a Thermo-Bob?

The Thermo-Bob is a machined, hard-anodized aluminum external thermostat with a coolant bypass. It allows coolant to bypass the radiator when cold, speeding warm-up and allowing your engine to run at the temperature it was designed for.

 

 

 

What is an Engine Jacket?

For snowbike riders, an engine jacket helps keeps snow off of the engine and keeps engine temps up especially for cold powder riding days.
