Big bore kit

[crisp]

Hi guys, considering fitting a big bore kit to my Forza 300!
Does anyone have experience of doing this?
Is a bigger throttle body & free flow exhaust required or will it work ok with just a bigger bore kit?

I don't have any experience with it but please do keep us posted

OK, who makes this kit and why do you want to go faster?

Can the variator handle faster? The clutch?

The tires are rated for this faster speed.

120 kmph is not fast enough for you?

Where do you live?

120 kmph is not fast enough for you?

The 2020 Forza 300 do almost 130km/h

It takes a much bigger engine to go much faster.

A 50cc increase will only get you a few miles per hour more.

Hardly worth it.

I’m living in Thailand & know of at least two places that supply big bore kit for our scooters.
I don’t want to get into the politics of why I want to go faster ..why didn’t you buy a bigger bike etc.
I’m here asking the questions about throttle bodies & free flow exhaust being required with a big bore kit?
Thank you, ride safe

I live in LOS also.
Asked the guy who did my 300 big bore on my CRF - he said change the pipe if you want it louder. Not required otherwise.
We did use the CBR300 throttle body and ECU
