Also surprised when he weighed the stock exhaust. Comes in at over 8kg.
Aftermarket can = 2.5kg. Maybe I need a new exhaust after all.
I wonder if going shopping is the best answer?
5 kg saving on a 200kg bike = 2.5% at a cost of £XXX plus £XXX less resale value and £x added to the insurance and whatever loss in MPG/range because all these systems turn petrol into noise.
5 kg saving on an 85kg rider = 5% high up weight, is cost neutral and gives benefit over the next 30-40 years.
Of course I'm not a lottery winner at his ideal weight, so what works for me may not work for everyone.
