Added a Cyclops Adventure Sports Motorcycle Tire Pressure Monitoring System (CIL-TPMS1).
I did this because of various readings that taught me I wanted to avoid low tire pressure / low speed crashes / get-offs / wobbles. (See / read at AdvRider : Faceplant).
Anyway, I check my tires before every ride, usually by just using my "calibrated foot" while stepping on the rim. Hey, it's better than nothing.
Now, I have a digital readout reference for a true pressure check for front and rear, at the handlebar, every time I ride. Perfect!
This kit is very good. The handlebar mounted unit is small, but the digital numbers are just big enough for me to read without glasses. They're LED type, and bright green. Bright enough for direct daylight viewing (I can read them in direct sunlight), and dim enough to be unobtrusive at night.
It's accurate. I used my best air pressure gauge, and set my tire pressures front and rear. When I got the readouts the first time, and since, the numbers match my settings with my gauge, front and rear.
This thing is simple to connect, and it was plug and play. If you have switched 12VDC at the bars already, then it's a 10 minute job to tap into that and make the connection to the bar unit.
The tire sensors take the place of your dust caps, and use batteries. They're light enough where you will not need any balance correction.
If you want cycle TPMS, this is a good kit.
