I must confess today that i have been riding dirt bikes and atvs all my life. Ive been on road bikes for 13 years and have froze many times here in Indiana. Well Saturday morning i left for a two day ride "2013 hnf ride" it was 28 degree's outside when i left and this was my first ride with heated grips. Someone smack me please. I feel stupid for never getting heated grips after all the years of freezing. 28 was nice and toasty And all i had on was leather gloves with vent holes in them and that was on low. High will about burn your fingers. It was the best 450-500 miles ive ridden. +++++++ probably the best $50 ive spent on a bike.
