If u check yr bathroom scales by say 5, 10, 30 kgs plus all weights, each time u use yr scale for yr bike, u willI have read differing views on the following method. Bathroom scales under front wheel, back wheel on block same height, balance bike with steady hand on handle bar after pulling upright from slight lean on wall. repeat for back wheel. Add two totals. The question is, can the result be true?
know the deviation factor or "bathroom-factor". What I found out by weighing my Norvin: It had the same
weight distribution, like my Honda RC31 (650 Hawk), which - in my opinion - is the best road holding bike
in the 60hp class. These bikes have a lighter front wheel load, than rear, and this seems to be for the changing
load with braking. If u study modern superbike tests, like BMW 1000RR, Honda CBR1000RR, etc. , they all have
heavier front wheel loads. I asume, that this is for compensating the aerial lift at speeds over 140mph, to keep
these bikes steady at full throttle on the motorway. As we do not have this kind of lift with our bikes, they
should not have the same weight distribution, like modern Super Bikes, to submit an enjoyable ride at lower
speeds, even on track. In other words, a good Vincent, on road or on track, should have abt 40% load on the
front and 60% on the rear. Original brakes in good nick are fine on a Comet, but will need some improvement
on the front with twins.
