Hi. I was thinking of getting a bore up kit for my 07 cbr 125 and the dealership said they could get me a 170cc big bore kit by Athena for about $500. Is it worth it? Will it increase top speed or torque?
I can get it to 125km/hr on the freeway with it stock right now but I would like to increase the bottom end if its at all possible??? I'll probably be getting a Hindle exhaust for it as well. I had an 09 ninja 250 before this and miss the speed, but the weight of the cbr 125 is perfect for me but it is too slow. I am still on my tip toes even with this bike; there is no lowering kit available anywhere it seems. Any suggestions are welcome and appreciated! I'd like to go on group rides again in the spring but I'm worried my bike is too slow. Thanks.
