Steve H (a member of this new forum who lives a few miles away from me in sunny Exmouth, Devon) and I each bought a 325cc big bore kit from Thumper Racing for our TTRs in 2010. I read about the 325cc kits years ago and my own view is that a 350cc 4-stroke e/start would be a pretty much ideal trail bike but you go...

Is anyone aware of a simple speedometer option for the TTR? Really only wanting speed...analog would be fine in order to keep it simple (both to use and to install, as I'm not especially mechanically-talented!). Thanks!

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. I think it flowed worse than the stock pipe and I needed to lower the needle (or raise the clip) to the highest setting to work properly. I deci...

These are M10 and mine kept coming loose despite using loctite and eventually sheared off on a ride out. A combination of tyre levers and lots of zip ties kept me going but rather than just replace it I drilled it and tapped out to M12 fine, then installed a 12.9 steel bolt. After 18 months it's problem f...

Hey guys, my name's Josh. I recently bought a (94/95?) TTR-250 Raid. This bike has been treated like crap, so I bought it as a project bike. Complete with a dodgey black spray-can paint job - yes - even on the motor. I've stripped all the paint from the frame so it looks a bit better. At the moment I'm more co...

I've recently put the original length shock linkage back on my Raid and noticed it now sits really far over on the sidestand... To the point where if there's a small incline i'm worried it will fall over. Is everyone elses like this? On the lowered link it was far happier on the sidestand..

Hi everyone, little new to my 2010 ttr250. I have dirt tires on right now, but I'm looking for something more street only tires(supermoto. Would need rims and tires. Not trying to break the bank, seems like anything good will cost me close to 1k? Links to the right fitment that will fit would be nice. Tha...

Can anyone tell me if any common aftermarket timing plugs fit the ttr.. it seams that some yzf and we ones fit from my research but can anyone tell me specifically if this is the case. Including year or models. I can't believe Yamaha would make lots of different sizes when they could use the same part for m...

Hi. I've picked up 2x ttr's one is an OE and the other a raid. I will be building one choosing the best bits of both. But what I want to do is fit the blue model tank seat and side panels.

I have a TTR Open Enduro. Please someone tell me what is the max tire size and rim size (SUPERMOTO) which can fix to original swing arm. I hope to replace only the rims and tires. Then I will fix them to original hubs and spares. I need the max tire size and rim size. Thank You!

Most of us use our TTRs for trail. track or road and therefore the requirements are very different to those of a race-tuned engine. I have been contacted by a kart racer who is using a TTR250 donk in his kart and has asked about tuning it to the max. This was my reply:Regarding the carb, the standard TTR car...
