Anyone have experience with the Doran Tire Pressure Monitor system as an alternative to the BMW version?

I'd like to have the BMW system, I was told it can't be retro-fitted to my '06... This seems like a reasonable alternative- thanks for the info!

Thanks for the info,

I will look into this for all my motor rigs.
Cool Gadget!

Here is another brand

Looks like an interesting system but no where could I find any reference to the battery life in the sensors. It appears that the batteries are not rechargeable and not replaceable. I wonder how long they last?

I have installed both Kisantech & Doran on my K1200GT (2007). Kisantech drove me crazy and the people from Kisantech were of no help! They offered to help when I told them "The system is being shipped back to them and I need an RMA!". I have installed 2 Kisantech on my bike until I GAVE up on the kit...and the company.

As for Doran, I have it on my back the past 2 months and it works like a charm. The part I don't like it takes a bit of a long time to send its reading to the display unit. It works as it is stated, it gives an alarm when the pressure is low and when the tires heat up the pressure goes up and the alarm go away.

BMW mechanic told me the sensor can be fitted on the inside of the wheel though. I have the transmitters installed on the valve and visible but who cares, it does the job.

The installation of Kisan is a bitch with the wires extending all the way to the transmitters from under the seat. The wireless bit on Doran beats Kisantech kit.


Buy Doran with confidence, I highly recommend it.

I had a SmarTire system fitted to my LT and it saved me a couple of times. They claimed a 5 year battery life, although I figure it would be more mileage dependent than time.

I got the TPM system on my GT and it works pretty well. After ~40-50K miles and just over a year, the front tire started failing to read sometimes, and the rear tire much more often. By 60K miles the rear failed about 1/2 the time, and the front about 1/3. I knew there was a battery in there somewhere, but couldn't find any reference to changing it out.

So at 18 months and 60K miles, I had to buy two new wheel sensors @ $130 front / $144 rear.

Didn't know that the OEM system had to be replaced. Duh. Just never thought of it. So if the sensors can be replaced, I guess it's just a board that snaps into the cluster for the readout?

The TPM system uses a control box tucked under the passenger seat. I believe there is an option for a TPM-only box or a TPM/alarm box. Obviously, there would be software changes, too.

It is also possible that early bikes (before TPM was an option) would need a whole new wiring harness, or they may have included the necessary plugs in all GT builds. You just never know until you go looking for them.

I doubt there's any instrument panel changes, as it uses the same display area for several functions. There would be a software update needed though.

Ken,
Is there no way to get that battery out of there without destroying the sensors?
