seriously, I couldn't ride out of site on a dark nite
, my point was given even rider skills, the bikes irrelevant and I don't think new punters on 5 years newer bikes will be hurling themselves into the scrub any faster than us on our older twin shocks
Never a truer word spoken.
Me and 4 mates had this discussion and tested the theory at a MX and flat track courses. 5 bikes ranged from 1990's YZ125, to '79 CR250, to hybrid XL500 in CR250 frame VMX racer to a 2015 KTM125SX.
All riders did timed laps on each bike. All riders posted different times from one another but almost exactly the same time individually on each bike.
Now, granted, there may be a different result with a top (or fitter) rider on board, but back in the day we were all pretty handy round an MX track. But the rider is in most cases the limiting factor in terms of speed. The biggest consideration would be the extra damage later model bikes can do to the track. But this is far less of an issue on enduro courses.
