Sport pro mk2

[k1v]

I am looking for a upgrade in power since sport pro has a discount im looking at it. Im upgrading from a streetrace and im curious about the reliability of the sport pro. If i generaly have a good crank, good mix and oil and dont rev it more than like 10-11k it should last atleast a season right?

It should be okay. How many miles are you doing in a season?
The sport pro is about the most extreme you can go without getting into mid race territory.
There are a lot of variables though. Like riding style and what exhaust you match it with?
If you have a Yasuni R or C16, the power will start to fall off before 11,000RPM.

well i ride kinda agressive ig, since i know the streetrace will not give out on me, but i have a gianelli reverse, maybe will upgrade to a c16 sometime or something bigger but not for sure, as for miles this season i think i will be doing like about 1000 miles

A better pipe would really improve the performance of the sport pro.
The performance with the C20 is very impressive. But you would really want a better crank to use that hard. www.pedparts.co.uk/c/asset/Stage6_Sport_Pro_MKII_Blog/Stage6_cylinder_kit.jpg
A thousand miles would be fine with this cylinder. I would perhaps check the rings after a couple of seasons riding.

yeah i should probably upgrade the pipe, atm i have a hpc crank tho its pretty fresh so i think it will be ok with the sport pro, also wont a better pipe kinda make the cylinder become more unreliable since the powerband is rised up the rpm?

Any increase in performance will have some effect on the maintenance and longevity of parts. But if you want better reliability and longer service intervals. You are better off sticking with a twin ring design.
