I am leaning towards moving from my 05 KTM 300 to a YZ 450 (07 or 08). I'd like to start spending time at the mx track. I will still be riding off-road and trails (some can get tight) and I would like to ask if any have had cooling issues in slower or more technical terrain. I did a search, and only found heating issues on older models. I assume that's a good omen. Any information is appreciated.

Only time I had an issue with my 06 YZ450 was while trail riding in slow sections then waiting for other riders at the end while idling. It would spit on the ground.

But all 4-stokes have this problem…I was just too lazy to kill it then kick it to life again
