Electronic valves aren't far away doing away with cams and timing chains buckets shims etc is the next leap forward.
Oh I would say they still are valid points. Smaller, lighter, faster with more and more electronics aids I think is where we are headed. Its interesting to look back anyway. To see the bike you can buy off the showroom now could have been the winning platform for a WSBK championship just a handful of years back.All the points are still valid though aren't they? Wonder if we'll be having the same discussion in another 15 years.
When the old timers tell me about the "game changers" and how they didn't think it could get better after things like DOHC. Or even stuff we consider to be so simple like gear dogs and shift drums which were cutting edge tech when they were new.
I have to admit, I didn't realize it was such an old post. But it's still funny how so many people (myself included) think we've "peaked" here and there. With the slow death of forums it is nice to discuss once in a while.
