Hammertone, TB3KE, Black, Gold
KLR600 and KLR650 1984 to 2018
This kit fits all years of the KLR600 and KLR650. It also fits the European-based KLR650C. It fits bikes with stock as well as aftermarket 6.6 gallon fuel tanks, but will NOT fit under the aftermarket 10 gallon ( 32 litre ) tanks.
Kawasaki cut corners in the KLR cooling system, and the Thermo-Bob modifies your cooling system to operate like automotive systems have for decades. In stock form, the KLR runs too cool when ridden in temps below about 80 – 85F. The cooler outside it is, the worse a stock bike is. Plus, the factory cooling system relies on surges of cold coolant every 30 seconds at the bottom of the cylinder to control engine temperature… just look at the plots of actual measured temps.
NOTE – For the customers with huge 32 litre fuel tanks – we have put together a “Thermo-Bob 3” Kit TB3KE. ( Australasian customers please note that is via order in only, email if you require that kit ) Thermo-Bob Kit Gold same if we have nil stock and you require email us on this as gold is rare !
NOTE – Gen III customers there is a new gen III 2022 kit, this new model is slightly different and has more options re a kit with a digital temperature gauge etc ( NOTE – NEW KITS ARE AVAILABLE NOW LISTED UNDER THIS SAME CATEGORY ‘ENGINE’ )
