Original Graves ctc ( Bandit) tire warmers with thermostats. You can leave them on all day and your tires will be ok. I recomend puttting them on 45 min or so before you go out . Or in between heats to keep your tires out of a heat cycle. Worked last them I used them. $ 150.00
Still available? 600's and 1000's use different size rears so if you can confirm they warmers will fit a 180-200 size rear I am I interested, or send me the model # and I'll look it up.
