Hi guys, as I've posted before, I have an insane and unhealthy obsession of grafting a twin disc setup into any bike I own. To that avail I want to swap out the wheels of my RC with those of either an Aprilia RS250 or an older generation Ducati. I believe either combination will be lighter than stock, especially the rear. My dilemma is whether I should stick with the stock 110/150 tire ratios or should I switch to a 120/160 combo? I believe some people use 120 fronts on their stock wheels with good results, so wouldn't that be a better choice on wider wheels? I have the following options charted out -
Please help me choose. I know this will only add weight to the bike and in possibly the worst place, but I'm doing this more to satiate my obsession than for any real performance gains. Also if I do it right, I might be able to keep that weight gain to a bare minimum or maybe even reduce the weight slightly. Titanium bolts/axles, lighter rotors, aluminium sprocket, etc, will all go a long way to reduce the rotating/unsprung mass, thus negating the effect(hopefully) of an extra front disc and calliper.
- Aprilia RS 250 MK1 - 3" front 4.5" rear
- Aprilia RS 250 MK2 - 3.5" front 4.5" rear
- Unspecified Ducati - 3.5" front 4.5/5" rear
