“I purchased them for my 2 bikes, one a KTM1290sa, when I put them on that they would not seal and let the tyres down, it appears that they will not seal as the KTM1290 has a short thread only part way down the stem, so any bike with a short thread on the OEM valve will have a problem. I cant change them as they have tyre pressure sensors in them that are OEM. I contacted the sellers, sent a video, they have not offered a refund or apology or acknowledgement. I then tried to get them on my DRZ, but the thread will not take, disappointed.”
“Great little item if motorcycle wheel fitted with straight tyre-valve so making air inflation easier. Don't leave it attached permanently though or wheel balance will be affected. When fitting new tyres always use angled tyre-valve at this stage. Keep this little item as a back-up only.”
