Hi
You can try this:
Vapor Digital Gauge at Trail Tech Home

A friend of mine has one and its very complete, easy to install and very reliable. You can buy it in USA.

 

Have a look at Koso

The KOSO RX-2N (10,000 RPM Range) is the one to go for on the Africa Twin – download the user manual from HERE (11Mb so be patient)

Available in Italy and USA

here's one fitted to an Africa Twin

Nice YouTube film of one in action KOSO RX-2N

 

:thumb: Thanks guys, I knew I could count on you. The information I found it very useful, now I need is to make a comparison of price and performance.
I hope to upload soon some pictures with my Queen and her new toy.
