I have Daytona Hot Grips on my XC250 and its real battery killer. But I used to turn them up on a highspeeds, they will get really warm, cable goes from front light switch which I have to turn on as I am riding because of law in my country. It has its on transmitter when tyou can turn them off, on - start position and on - heat. on start position they are warming up and on the third position they stay on the constant temp. If you will trying to connect them, try to use own cable, do not connect them as I have. Its really annoying when I forget to turn them off and they are draining battery all the way through city lights crossroads etc. I have permanently turned battery notification on panel on 3 days after recharging. Will do something with them in a month, if you want I can post what I ve done after it will be finished.
