Whilst the curves look good (just spend an hour going over his facebook page)
They all seem to fall over at 5000-5500rpm on a small motor.... gives most of the results I saw a 2000rpm powerband at best.
So bulk midrange is great for a lot of guys. but for me, having to shift up at 5000rpm on a motor that revs to 7500 would annoy the shit out of me,because I'd go from having 400kw to >200 after every gear change
