You'll want that phone in your pocket if you go down separated from your bike and laying hurt in a ditch.
I tent to agree, watch this guy, separated from his gs, trying to catch a breath, his buddies went ahead, even if they turn around, they couldn't even see him in the ditch, at timestamp 4:53 he is saying he was lucky he had his cell phone in his pocket, it's one of those life or death situations, a phone in your pocket may become your life line. Geez I hope nobody ever has to go through this, this guy had multiple surgeries, and seriously injured and disabled, not in the wheelchair but almost.You'll want that phone in your pocket if you go down separated from your bike and laying hurt in a ditch.
The ones linked earlier at kurvygurl are metal. No flexing at all. Your mechanic may hve been thinking about cheap-o rubber ones.When I was getting a new tire mounted last weekend, I asked about 90-degree stems. The mechanic said that the "sideways" stem can flex over time (think of the high speed pushing the horizontal part of the stem outwards towards the rim, then flexing back as you slow down) and eventually leak - so he didn't recommend them. Your mileage may vary, but that was his stated reason for sticking with "standard" valve stems.
Looking good, does it show both tires pressure and temperature at all time?Damir, I can vouch for the Hawkshead unit. tpms.ca is their website. I do run 90 degree Ariete valve stems but I will be switching to the Hawkshead .453 T-valve stems at the next tire
change. Here are a couple of pictures. Please excuse the dust, I do live in the country. I have been using this for over a year with no issues. Uncle Phil has a very good write up on these
over on the st-owners website. He runs Hawkshead on 4 of his ST1100's.

That's a great information Moos***, so far the info was that FJR hole was 11.3mm, your measurement is considerably smaller.
I guess.... if one really feels it necessary, it won't cause any harm. But I've been using metal valve stems on all my vehicles for 30+ yrs and never have I seen or heard of anyone having this problem. The 2 different screw-on TPMS I've seen are plastic.If you use metal valve cap or external TPMS installed, unscrew them from time to time so they won't seize. I would apply some type of lube/oil on the valve stem before inserting the TPMS, especially if you ride in the on salted winter roads to prevent corrosion build up.
