will they work on atvs and are they accurate also where do i install it

 

They will but you will have to extend the sensor wire..and you mount the magnet on the rim and the sensor anywhere that is close enough and will work..you will just have to play with it. I had one on mine but when i extended the wire the electrical tape wasn't enough to keep all the crud out and it didn't work right...so i got rid of it and got a garmin eTrex GPS and its awesome..i would say go for that!!! For the bike speedo you have to figure out the number to put in to program it for the size tires you have but it is possible. Hope i helped some.

 

they work awesome ! i have one on my 250X and it it VERY accurate and dependable . I bought it on Ebay for $43 . there are more on there if you want one . if you have a 400ex 300ex or 250X the number you need to put in is 168 . good luck !

 

I put a 20 dollar wal mart bike speedo on my Blaster. I siliconed the sensor to my disk and mounted the other sensor to the axle housing. It worked very fine but the cable kept breaking. But if you where to get one get a speedo made for atv's. You can find a very nice one in rockymountain.com. Or just save a little more and get a gps. Many more uses and more accurate.
