Mechanical speedometers are so........yesterday!
There are a whole new batch of electronic speedometers that not only offer the ability to get accurate speed information, you can get accurate odometer readings, trip odometer(s), engine and ambient air temperatures, time logs, altitude readings, turn signal and high beam indicators, shift and engine red line lights, etc. They are not too hard to install, and as time passes they are getting more affordable Entry level one are about $ 200 to install and some really fancy ones go for over $ 400. Some of the more recent ones even have conventional looking cases and swing needles for the tachometer. If accuracy is important and and money issue are not.....the GPS ones are really nice.
A few years ago all the electronic speedometers looked like lab equipment and did not look good on a bike - but the new ones look more like gauges we are used to seeing on motorcycles.
The fact is that s $ 60 mechanical speedometer is not going to read accurately on the wide range of bikes....maybe once in a while someone will get lucky and have the right gear ratio and tires size and it will read close enough.....and if you are building a simple bobber/rat bike and want a small speedo to check speed once in a while....they might read close enough. But if you want something useful and do a lot of riding.....by the time you buy a mechanical speedo, tach, and the cable to get them to work on the Savage - you will have spent about as much as an entry lever electronic speedo/tach will cost.
So do these electronic speedometers work? If so where do you find them and what model
