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 thought I would upload an easy way to install an on/off switch for the head-light. The reason I have done this is because the Cobra websites way is absolute hogwash (in my books). It gets the blue wires the wrong way on the switch in the diagram given. Also they ''butcher'' the main wiring harness? Rat...

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 dug the USD forks out & took few numbers for the conversion into the TTR.... It turns out the 05 YZF250 USD forks use the same ID bearings as the TTR... 28mm Top / 30mm bottom... Even the steering stops look to be in about the right place.. The YZF forks are 40mm longer but theres enough un-tapperd are...

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...

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. I tried various ways to do this on two different TTR's but had the same result both times. The problem with this...

Do any of you guys run an Anderson plug on your bikes directly from the battery? If so where did you mount it? I'm thinking of putting one on my TTR. Reason being to be able to trickle charge the bike with out removing the plastics. Could also plug a mini jump starter pack in it or even a little 12v air compres...

My bike has the original Tekei carb bored out, and with a ported and decked head, high comp 2mm OS piston, GYTR muffler and snorkel removed from airbox.

I just bought a very nice 2002 TTR250 in great shape and I was wondering if an aftermarket pipe would really help, or should I just open up the stock pipe? I don't mind spending a little money if it truly makes a difference, but I don't care about the weight reduction and appearance, etc. I would only wan...

Hello everyone. Finally I found a bike I wanted. It's arriving in few days. Things I will need to sort first is mirrors - the bike don't have any. As my budget is tight, Double Take is not an option, and perhaps not a necessity for now - mainly it will be thumping on paved roads. Anyone had good success w...
