2 Pistons 99mm (1100cc) "HC"
(1100cc) ratio 11,8 : 1
for valves 34/29mm (original).
for "HighLift" camshaft.

Camshafts High-Lift
high torque, gain over the whole revolution range,
problem free idle speed,
for all R1100/1150 models.
Due to the high valve acceleration is the use of lightweight cups required.
These cam is the absolute maximum you can do.
A little more noises of the valve drive are unavoidable.

4 Lightweight Cups / Bukket Type Tappets
from 40 grams original to 26 grams !
35% off !

8 Lightweight Valve Adjust Screws

All this will result in this:

Approx. 112 hp (also for 1100 kit)
Loss of 700 grams of moving parts
Keep the original cylinders
Can rev 9000 rpm

very interesting, as I read it I take it as the diagram shows 1150cc and you said comparable to 1100cc as well..... would this mean that the 1100 would be making the 112bhp at higher revs to get the extra torque to do so or have they modified the valve timing to compensate?

I know 50cc's aint much difference but we live in a culture that says bigger is better

is there a website link?

just noticed, Pony Shire reading....... IIRC this is not correct BHP......

112PS => 110.4656 BHP

113.3PS => 111.74779

ie PS too BHP is PS x 0.9863
