New tubes

[bryanchurch06]

I did a search for this info before posting this and had no luck finding the info so if anyone can help I'd appreciate it, I'm ordering new kenda 262 tires and want to order new tubes also so my question is the valve stem tr4 or tr6? These are the tubes I'm considering btw, thanks Bryan

TR-4 and TR-6 are interchangeable. IRC and Dunlop use TR-4 valve stems, most other brands use TR-6. The OEM tubes are IRC (#T20049) and have a TR-4 valve stem. For the CT125's rims the valve stem needs to be centered, which is standard for TR-4/TR-6. If you see the terms OC/off-center or offset, it's not the right tube.

The rubber base of a TR-4 is a circle, the rubber base of a TR-6 is oval.
