I ride a BMW R1200RT. Completed a ride last year in Montana, Canada, Wyoming and such. I was concerned about keeping warm before leaving east coast as I did not want any day of riding with regrets about keeping warm. I did not have time to screw around with forums or blogs at that time , so I turned to Revzilla online and ordered First gear jacket liner, gloves, pant liner, socks and a remote controller that I could Velcro to the clutch cover and twirl as I rode. The bike has heated grips and heated seat, either can cook food if maxed out. First day of real cold riding I put on all 4 pieces of heated gear......the remote was set to heat jacket/gloves on one knob, while the pants/socks were controlled on the other knob. Oh yeah, I wear Joe Rocket Sonic leather LT jacket and Aerostich custom fancy pants (cant remember model) and Chippawa mc boots. Outside temp in the 30s, all gear on med heat, grips on med, we set out for "Going to the Sun Road". Pretty soon it became evident that I was going to sweat and cook into a toasty mess. However the gloves were on, but not providing heat I needed, and the lower heat pants/socks was not needed at all. So I learned to ride with an open zipped jacket to allow heat to gloves, as the outside of your hands will freeze while gripping on a red hot grip. Since the trip, I have put the gloves on one knob and the jacket liner on the other and have somewhat gotten satisfaction. I don't seem to need lower extremity heat, but stowed in case. The first gear leather gloves are okay but don't heat the thumb at all. So I recommend the First gear jacket liner, first gear remote, the gloves are okay, but I want thumb heat.
