Simply question, how do I completely remove the rear indicators on my bike (2004 TTR-250) I don't want to ruin any of the electrics so I have to be sure. I removed the brackets and the indicators are now dangling from the wire. What do I do next?

These specs are based on the lowest TTR250 specs and some models may have a rating than specified below. If your model specs are different to below refer to those specs for maximum Headlight/tail-light capacity. I would not recommend running more than two Tail-light bulbs: 12V 5W/21W (or the equ...

I have just done a bit of research for a customer so thought I might as well share the information and maybe there are owners on here that can add to it or correct it - please!The only big-bore kit I have found for the TTR250 is from Thumper Racing in the States - see http://thumperracing.net/index.php?r...

I had a request from a guy who is short in the leg (his description!) to try a lowered TTR. I fitted a lowering link, wound the rear shock spring off just a tad, reversed the handlebar clamps to allow the front forks to be dropped up through by 21.3mm, and fitted a sculpted lowered seat. This achieved a new s...

This has to be the easiest USD upgrade you could find.... A straight bolt-in fit only took me 4 hours included stripping the TTR front end out of the bike.... [URL=http://s1244.photobucket.com/user/petenz1/media/SAM_0144.jpg.html][IMG]https://i1244.photobucket.com/albums/gg563/pe...

I thought I would share this simple air-box mod with other owners. I had previously tried (twice) to cut down the air duct/snorkel to gain performance. Both times I have had the same result.

So I've recently fitted a shiny new FMF Powercore 4 along with a FMF quiet core. Previously I'd fitted another after market pipe but was unhappy with the results.

These are M10 and mine kept coming loose despite using loctite and eventually sheared off on a ride out.

After 18 months it's problem f...
