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...

I have been in contact with Hagon Shocks about them developing a rear shock for the TTR for a while now. Today I dropped my bike off for the work to begin. I will get it back in around 2 weeks and keep you all updated on how it goes. -- Edited by mikemikettr250bike on Tuesday 9th of November 2021 05:44:30...

I am very pleased with my 02 street legal TTR250.....with one exception. The forks are way too soft. The front end dives when you touch the front brake. I was told to run 4psi and that is what I am running. Can I buy spacers to make the springs stiffer, or buy stiffer springs? Thanks!

Hello Board Members, our 1999 TT-R250 has a WR250f fork mounted. This conversion seems to work great, but the bike is to be lowered and therefore I would like to know how high it is in the front at the top of the steering head and in the middle of the handlebars with an original fork. That would help me to k...

I've always wanted a higher seat on the TTR. Although the original seat is lower and easier to put a foot down in technical situations, I feel a bit cramped and then tend to cramp in the legs during and after long rides on the TTR250. This doesn't happen on modern bikes I also ride. Anyway new seat is on a...

I wanted to see if I could reduce the slope towards the tank on my Raid seat, while also getting some added padding and making it a little higher in the process.

As the title suggests I have increased the power to weight ratio on the TTR, perhaps a bend of the truth a little.

Got a used GYTR tailpipe. Are some tailpipes just a slip on with no clamp needed ? Looks as though there never as been any clamp.

I really like my 2005 TTR250, it was the one bike I have always regretted not buying new when I had the chance. I bought this one 3 years ago having run a TT600RE for quite a few years, I ran them both for while whilst deciding which one to keep. For me, the 250 was the clear winner, lighter, 6 gears, better on t...

Talking to a friend of mine the other day we discussed why the majority of bikes have cable operated clutches. He rides trials and his Montesa (Honda engine) has an hydraulic clutch and it is much lighter than a cable one even when we'll lubricated. Anyone any thoughts please?

The original front line on my '94 OE was bulging slightly under pressure near the bottom banjo so I ordered a replacement braided line from ebay listed as 'TTR250 1994 front brake line'.

Hello good night, I recently bought a ttr 250 blue from 2003. I am delighted with the bike but it is not very good and they tell me that it must have some cap on the exhaust pipe, someone would give me a link on how to remove that cap so that it bike go better. Thank you.
