If it was not equipped with them the only thing I can think of is maybe the Dark Horse Chieftains might not have came with them. But I would be very surprised at that. You don't at a TPMS warning when going down the road? Dean

Probably going to need a tire replacement this winter and was going to change out the TPMS sensors too. Unfortunately, AliExpress doesn’t carry the correct sensor any longer (part # 2412417). Plus, the IM on-line parts book shows 2412417 being replace by 2208712 on every production year. I can’t find the new part number for sale anyplace except IM (shocking, huh).

However, the BMW motorcycle TPMS sensors are made by the same manufacturer (Schrader), look identical, and they operate on the same frequency (433 MHz) as the IM ones. So, chime-in if you have any expertise on why these would/would not work.

Are you sure the frequency of the sensors is the 433 MHz? My learning tool does both 315MHz and the 433MHz but I know the two are not interchangeable. Trying to find something that shows what the original sensors worked at but no joy. Dean

Found it. It is the 433 frequency. I did find them on Ali Express. Try this link. Dean

Just an FYI - I ordered a set of these about a year ago from Ali Express and it took about 30 days for the shipment to arrive from China. When I took them to the shop to have them installed the tech found that both of them didn't work and I ended up having to buy OEM ones anyway. Buy at your own risk 🙁

I purchased a couple of these last year. Just put the last one on recently when I changed out my back tire. Both are working fine. No issues doing the learning process. At this price I could purchase a dozen and meet the Polaris price. Having a bad one or two in the lot would still not be much of a problem. If I had a bad experience I certainly would not forward them to others. Dean
