Guys dont forget that assuming you weigh 60 Kg, approx 10.5 st, on the YZF-R125, a total of some 200Kg an increase of 1-2 hp is a gain of 5-10 bhp per ton an increase from 75BHP per ton to 85...
The standard exhaust weighs something like 4 kilos and a leovince, scorpion weighs a quarter of that which again increases the bhp/ton
This bike may be restricted electronicaly but as with a car engine the increase in power comes from tuning..
I have noticed on mine the top of the air filter box has the inlets on the back of it. I've not had the tank off so cannot see the shape of the filter box but it looks like it may be possible to rotate the top through 180 degrees and feed cool air into the box. This could achieve a ram effect!
Can anyone confirm if the top of the box can be rotated?
