TPMS

[TrevKerr]

Gamin TPMS installed.....although after one day the rear sensor is showing the battery as low ! There have been reports of this......but seems to work ok.
I have the rear tyre set to 42psi with a warning to come on if it drops below 40psi and the front is set to 40psi with a warning to come on at 36psi.
Seems to be trial and error with the tyre pressures as 42 42 seems very hard although thats what manufacturers recommend.

Good info. I assume they're giving accurate readings (or you wouldn't bother telling us about them).

Yes I have a digital tyre pressure gauge and they are matching so all seems well......my only criticism is the cost.

42 psi is the recommendation at maximum load capacity (2up, maybe with some gear). Way too hard for solo riding IMO.

42 psi is the only recommended pressure I've seen. I agree it's pretty high. Other touring bikes have different pressures for different loads listed.

On the bridgestone site they are recommending less on the front, I think it is 2.5 front and 2.9 rear. Who do you trust, the tyre maker or the bike manufacturer?

I have BT-023 on her at the mo but I am going to the Isle of Man on Sunday and might chance S21s again.

Right. Here's the spec directly from the shop manual:

Air Pressure (when Cold)

Front:
Up to 195 kg (430 lb) load:
290 kPa (2.90 kgf/cm², 42 psi)

Rear:
Up to 195 kg (430 lb) load:
290 kPa (2.90 kgf/cm², 42 psi)

feel free to run at 42 psi riding solo, but it's like riding stones for tires.

I checked tire pressure Sunday before my 200 mile ride. Front and rear were 40 psi. Hmmm, I think they were set to 42 psi at the dealer and their gauge is off by 2 psi compared to mine (my gauge is spot on, right?). I adjusted the front to 36 and rear to 42, what I was used to on my previous Triumph Sprint STs. The handling was fine during the ride and the bumps were apparent as before. I encountered some slippery tar snakes around Sedona though I think the slipperiness had to do with temperature (~90F) vice tire pressure.

did you balance the wheels after adding the TPMS? i mean at that power and rpms, you wont want to have unbalanced wheels

Reply no didnt rebalance wheels and everything seems ok
