Thinking of getting a QAT.. couple of questions regards quick action throttles: 1) Some throttle kits offer different tubes sizes (HONDA CBR1000RR Fireblade 04-07 Quick Action Throttle Race Track Bike | eBay) does that mean that my Oxford heated grips will only work with one of them, or is the "tube size" refering the cam / pulley on the tube? not giving up the heated grips, I use them all the time! 2) What is the best size / brand that worked for you? should I got for HRC or Active from Calsport etc.. there must be soome that have proved impossible to live with on the road - where mine will be used 100% of the time. cheers!
