Okay, so here are my thoughts… The new Honda CRF450R has been said to have around 56bhp, which is slightly misleading… As most people know, it’s not a vehicles true measurement of power, as it’s measured at the crankshaft… After that power has made it’s way to the transmission it’s lost a fair few ponies… So I took my brand spanking new bike to the dyno machine (Rolling road.) To set about finding it’s real power, which was not disappointing at all!! I found that it’s stock form was around 50 true horses at the wheel!! Which considering the loss from the bearing drag, rod and crankshaft windage losses, oil film drag, etc was rather good, not to mention the bike was new and I really didn’t want to push it too hard, so I recon it could have easily squezzed a good 2 or 3 more horses out… So I thought to myself with the low weight and high power of this beast, how could I make it even faster!! After many hours searching the web I found that the well known company “Yoshimura” work very closely with Honda’s offroad beasts!! I looked over their products and found that by spending around $5750 would easily pack in 15 Mighty Stallions with their stage 3 engine rebuild and full exhaust system Taking into account teams racing in Nascar events spend around $100,000.00 for 1 more horse it put a smile on my face!! And let's just say it'll need a lot more fine tuning!! And I thought to myself… It’s just not enough, and like flash it hit me, one of the most used power aids! TURBO-CHARGING!! I read somewhere that just by fitting a turbo kit you can expect to get from between 30 – 60% more power… Well If we can add 60% onto the beast it’ll easily fly past the 100 horses mark… And all this from a medium sized single cylinder?!?! AWESOME!! Obviously this is all theory, doing such would seriously damage any bike’s reliability!! And let’s agree that it’s a little ambitious… Although certain WRC and other rally machines are pumping out between 450-550hp, that’s just WOW from a 2 litre engine… So maybe it is possible? However, with just the 15hp “Yoshimura” can add they do stress Very regular servicing… For example they measure intervals in a number of hours raced.
