Reply to Buying one case half? 4/21/2022 6:10 PM

From personal experience on a 05 YZ125. Put a hole in the left side case from a clutch push rod issue. Replaced just one half. This was done approximately 40hrs ago, no issues. You should be fine by just replacing one side.

Reply to ECU remap? 4/7/2021 4:38 AM

I figured I'd chime in but i'll be upfront to say that I do not have any experience with a reflashed stock ECU. Input coming from having a 2016 yz450f and a 2019 yz250f. The GYTR tuner (similar platform as the new WiFi set up for your phone on the 2019-current) ... more »

Any master cylinder from early 2000's and up ktm will work. Use the stock YZ line with the brembo banjo bolts on the MC. Part number 54813001200 is one of the more common ktm master cylinders used.

Reply to Broken chain, leaking countershaft seal. 5/26/2019 3:01 PM

Thanks Paw Paw. I will get that all replaced. Am I overly paranoid now with a clip style master link failing or should I look into a rivit style master link as this is a common problem? I've never had a clip style failure before.

New thread Broken chain, leaking countershaft seal. 5/26/2019 1:25 PM

Had an issue with the clip style master link coming off my chain, chain let go, took out/mauled the case saver and got jammed against the case. In the process of inspecting it I found some oil running down the inside of the case. At first I thought the

Silencer for the 250's have two mounts, the 125's only have one mount. As far as I know it has always been this way.

Reply to Giuseppe Luongo on Red Bud and his view on why Tomac might never race MXGP! 9/25/2018 7:17 AM

"If Tomac gave MXGP a proper go, it would add that next level prestigious the series deserves." Its not about what the MXGP can do for Tomac, rather what Tomac can do for the MXGP? I believe there is a reason why an MXGP rider wanted to race a US national ... more »

Reply to Why so few initial tests on the 2019 KTM 450 SX-F? 7/12/2018 4:31 AM

I am not up on the latest KTM stuff, but isn't the 2018 FE the new 450? I would say there is no factory edition 250 or 350 for 2018, the 2019 250 and 350 are "all new" and the 2019 450 would be the same as the 2018 factory edition. If your looking for ... more »

Yes, I should have specified that I was pertaining to the blue one but it looks like everyone has them on back order.

New thread YZ Stadium Plate 6/4/2018 7:05 PM

Noticed the cycle trader team running a different style stadium plate. A little digging results in a new UFO stadium plate. I like how the brake line is made/routed behind the number plate. Anyone know who has them in stock, in the USA not Europe?
