Looking for improved torque and/or power from my Sherco 125.  I don't want to get a bigger bike/engine because I don't want to loose the agile handling.

Anyone fitted Boyesen Power Reeds to their 125?  What were the effects?  Would you recommend installing them?

 

What about a High or Very High S3 cylinder head insert?  Any performance gain?

Thanks 

Hi, when first got my 07 125, it had so much go I retuned it a bit. It came with a 200 top end and a flat slide carby. I also fitted a TRP shock...magic.

Cheers Taff

I can't vouch for the 125 but the carbon reeds do give more torque and quicker revs in the 300's.

 

A high compression insert will give it more grunt off the bottom and make it it more snappy at low revs.

 

I have a head insert for a 125 sherco, I think its a high or very high, I'll have to double check, I got it used as a complete head but only wanted the outer part, You can have it if you want it, It's just gathering dust on the shelf.
