Im sure there must be a thread on here but here goes anyways,whatopinions do you guys/girls have on the bigbores? ie is there a noticeable torque increase or a smoother uptake down low? And are they reasonable value for money relative to performance gains? I have a 15 4rt 260.

I don't know if it's much more expensive to just buy a 300 RR.

It's got a longer stroke, so I guess it'll have even somewhat more torque than just with a bigger bore, like the S3/Mitani kit.

just my thoughts 

A bigbore kit is less than 25% of the cost of trading up to an RR,much as I would like one it not going to happen.

I rode a 300 back in 2012 at a test day, It has loads more grunt but it's still on the lazy side, runs out of revs like a diesel. Unless your an expert rider you will get no benefit or extra grip. The 260 is more than enough for most who ride them, I see many people who are just a passenger, being taken for a walk by the bike!!!!

 

Spend the money on an s3 pipe and throttle body mods, Makes a hell of a difference for less money.

Only a header pipe? is the stock silencer good enough then? I have a ptb on her but its not a dual map.

The S3 pipe works, Ive ridden one before and after.
