I was fortunate enough to find a system that includes theft protection, doesn’t require tire removal for battery changes, doesn’t require a separate display or visible smartphone, doesn’t require me to be linked to or using my 595LM, and it monitors both temp and pressure.

Fobo bike. Luck was all it was. I bought mine when they were brand new. Still using that set, albeit on a newer FJR.

I do my own tire changes and balancing so my TPMS only cost me 50 bucks for the unit and 20 bucks for the "T" valves. I was concerned about the extra weight of the T valves AND TPMS button, so I balanced the front wheel BEFORE I installed the tire. It took 3 ounces of weight to balance the wheel by itself and only another 1/2 ounce after the tire was installed. I don't remember how much weight the rear tire took, but the valve and the button are so much less, as a percentage, on the rear, I don't think it matters.

P.S. I checked the weights on the front tire and I was wrong, I put 2 ounces on {4 - 1/4 ounce weights on each side of the wheel, opposite the "T' valve and the TPMS button. And then put {2}- 1/4 ounce weights after I put the tire on.

Rather than deal with Yet Another Gizmo I bit the bullet buying two Garmin TPMS sensors for $70 each. Smaller than any other TPMS on the market. No problems having to take them off to put air in tires the past 50,000 miles. But I do keep spare batteries in my saddlebags.

The Best Solution would be a machined mount for TPMS in the wheel casting with external access for battery replacement. Something inside for theft deterrence yet outside for battery replacement without having to remove the tire.

Even better yet, I have heard there are a few "self winding" TPMS sensors which use a weight or something to generate power from wheel motion.
Great ideas!

Their service rate is $100/hr which I thought was very high, although they generously offered to install the new rear tire for free since they had to remove the old one anyway to install the TPMS, just P’d me off to the max so I bought a new Nomar tire changer to do it myself, expensive TPMS but well worth it overall, its paid for itself,,, in just lowered blood pressure if nothing else.
I would be looking for a new dealer. I had my T valves installed when I needed new tires anyway. They charged nothing extra to install the valves. And they have the best labor rate I have seen in quite a while to mount tires if you buy the tires from them.

When I first started dealing with them I asked the owner if they will install a tire that I bring in. She said they will at the higher (but still reasonable) rate, but asked if I would give them a chance to sell me the tires too. They have worked with me on price and have gotten within $8-10 of what I can buy them online. It does cost me a little more because of taxes, but I want to develop a good relationship with them. I have learned over my considerable years that relationships with with dealers can be very beneficial.

3 ounces? Ouch! That is (12) 7g weights! My worst so far was the Shinko 016 rear with (7) 7g (1/4 oz) weights. In general I'm not seeing any pattern of heavy side vs valve stem and my Garmin TPMS. Weights don't go near the valve stem but often 90° around.

Thought to order more stick-on weights the other day and was surprised to find all the reasonably priced sources were out of stock of the Motion-Pro brand. Running low on black ones, still have a full box of gray. I might just search for some good double-sided foam tape because I kept my used weights.

Three years ago when I bought my No-Mar CH200 kit it included what was apparently their cheapest balancer. Mine is long gone from their catalog because it was pathetic. No 2 of the 4 bearings were in the same plane or parallel to another. Shoulder screws affixed to light stamped steel with a nut cocked in the hole. The stamped steel was bowed. And left arm twisted with respect to right. Drilled and tapped holes in a couple 1/4" aluminum scraps, then attached to the stand. This holds 2 bearings in same plane. Then before use a carpenter's square helps me tweak the arms so the left and right bearings are parallel. It gets the job done but the bearings are starting to need attention as sometimes the wheel bearings turn freer. Is good enough to determine whether the wheel needs that last 7g weight or not. And sometimes the right solution is two 7g weights 6" apart because immediately adjacent is too much.

Decided I had enough of that and ordered a Marc Parnes balancer. Haven't balanced a wheel yet, but am impressed. Marc's cones have thumb screws which are an obvious imbalance. So what, just put the thumbscrews 180° apart. My old balancer wouldn't have noticed the thumbscrews only an inch radius from the axle center but just playing on the kitchen table Marc's does! If they are closer than 120° then the heavy side goes down. Thats sensitive!

Here is a temporary fix (Honda forum by Deano) to use the TPMS on rubber stems, that (I think) should ONLY be used until the next tire change, when the proper metal stem should be installed. Interesting fix but not sure how safe it is.

https://www.nc700-forum.com/forum/ti...e-stems-2.html

FOBO also makes "tire stem stabilizer" that will do the same thing, prevent the stem from flexing caused due to the "heavy" TPMS transmiter cap.

I am glad I saw this thread. I just bought my 2014 and put the Fobo system on it. Went out and looked at my valve stems and both are bent. I will take the Fobo off until I change tires, which will be about 3k more miles and change to the metal valve stem
