on mine with the jagg cooler its between 30-50 degrees cooler(according to src temp dipstick). where I noticed that the most is when trail riding in the heat and riding hard, the oil will get hot enough to burn the grease out of the steering head bearings(because thats the oil tank, in case you didnt know?). it would leak out the lower neck seal and run down the back of the front fender. with the cooler that doesnt happen at all. basic automotive common sense says that cooler oil means longer engine life. BTW-oil seems to look and smell better with the cooler at changes too.
