TTR230 Engine Performance Mods

3 posts in this topic

'Seen a lot of inquiries on what performance mods are available for the TTR230. Here's a few for those interested:

EASTERN USA

www.xtrememinis.com

While they don't advertise mods for the TTR230 specifically, I contacted them. They do crank, flywheel, and hear porting services for the 230. They will also soon be providing details on a full 250cc upgrade.

WEST COAST

www.xr100.com/ttr230.htm

Engines Only. Big bore kits, intake mods, headwork & camshaft mods, flywheel mods. They seem a bit more pricey than xtrememinis though, don't know if the services are better.

www.webcamshafts.com

Web Cam Racing Cams. Call them first - they'll do camshaft work for the TTR225 which has the same engine as the 230 so you'll need to make sure.

There's still big gaps for other aftermarket parts, though. I guess in time those things will start surfacing as well.
