If you don't want to drill the hole in the bike, you can use a longer screew on the plastic brake guard attachment, and attach the hub spin detector side with that screw, then the trailtech peice just sits under the brake guard plastic, attached by the longer screw, then i just used the magnetic screw (provided by trailtech) as the rotation monitor source, instead of the other round magnet. Then to keep my other trip meter on, I just strapped on the trailtech mount on top off it with a strong zip tie (this tip may not be that good, but mine hs stayed on so far) and it tracks good bike speed there fairly accurately.
YEAH!
great tip!
my dad had that trail tech computer installed on his 450 the same way!
it works awesome if you learn to use it unfortunately i didnt but it looked very cool
I removed my original trip meter from the original mount and reattached it using the left mounting hole on the meter and the right bracket hole. It sets a little crooked behind the plastic, but I still have it, when I need it.
