Thanks for that info' (yea, a lightened flywheel would be nice).
The reason for my question is that there is obviously a lot of talk about the supposed / presumed benefit of the 620 and I was trying to establish if anyone had 'gone all the way' with the BB so we could make a direct comparrison.
My interpretation of the rules, the thinking behind the rules and the other supporting tech' info' has always led me to believe that a BB would require all the possible mods' in order to be comparable with a 620.
Therefore my take on the technical options has always been; EITHER buy an expensive donor 620, don't fiddle with it much ('cos the rules won't let you) and just race it, OR buy a cheap donor bike (600) and be prepared to do a lot of creative / highly skilled (and ultimately also expensive) technical fiddling to make it competative.
Having said all that, a 'hot' BB would deliver its power / torque in a different way to a 620 so there would probably be some circuits that favoured the 620 and some that favoured the BB - perhaps.
I chose a 620 because I didn't want the hastle of extensive engine work, I do not have the skill to do it myself and I thought it would probably work out more expensive in the long run to pay someone else to do it for me. There was also the little matter of bugger all time between me raising the funding and the 1st meeting.
Judging from the response to my question and the fact that the series is still only two meetings old, it seems to me that there has not yet been enough time / development to prove whether or not a "full monty" BB can be competative.
Just a thought.  |
