KTM 2007 525 exc-G Racing

Recommended Posts

I just bought a 2007 KTM 525 KTM exc. Street Legal. I Changed the Exhaust with a Ktm Racing Can, thats not so baffled. Rejet the carb with the JT Jetting. The bike runs owsome. Gearing is a little tall, i wanted to change The sprockets to get a lower gearing. Dirt Bike Magazine for March has the 450 exc Changed from a 15 to 45 to a 14 to 50. and still does 90. What do you guys think? Also how do i know how long of a chain to buy? Help me.

Thank you

You'll need a 520 X 118 for 14/50 gearing.

What brand of chain/sprockets are you after? Let the TT Store know if we can help you.

Checkout my review of the Ironman sprockets in the TT Tested section. I've found them pretty hard to beat.
