If 60 is wildly optimistic for crank hp, what is the correct bhp rating for an 850 Commando then?
Also, what should the proper number be for a non Combat 750?
Glen
but I am going to complain about the 115mph top end, no way,
I have owned or ridden 9 stock Mark3's and the most they saw was 108mph
Probably one of those that were found still in crates in Belgium.
40rwhp or less is my own take on the most quoted figures I’ve seen.
10% or 5bhp being the figure often quoted by some as the amount lost twixt crank and wheel (Dave Nourish said it was 5bhp on his engines, I’d guess that fairly representative to Commandos).
So, a good 850 should be around 45bhp at the crank IF all of the above is correct.
None of the above is very scientific however, more like hearsay. Certainly wouldn’t stand up in court !!
The other day I needed to get past a car and what with the small space and poor judgement I had to go past 6k in second and third.
Everyone survived and I was rather surprised to find quite a bit of power up there and that it didnt tail off at all. So that you dont have
to ask, Andover peashooters on single pipes, stock ham can filter, amal premiums, 260 mains, Fullauto head, Pazon Altair, TTI box and
me weighing in at nine stone full kit. Rest of the bike is stock.
Fast Eddie,Both bikes in the pics are mk3s.
Any chance of slipping that Silk 700 in your luggage ? ( they are easier to carry than a Commando)
