New thread Weighing my options for vintage -- 99-01 vs 02-04 YZ 125s 8/23/2021 3:59 PM

I'm looking at both 99-01 YZ 125s as well as 02-04. I'm going to use it for occasional AHRMA racing in Millenium class, but also plan to ride it regularly as a "cross training" bike for a break from my four stroke. I owned an 04 for a while and loved ... more »

Okay, so I'm a bottom feeder and haven't bought a new bike in a long time. A Husky dealer in NC says they charge $485 in shipping, $400 for assembly and $340 for "dock fee" in addition of course to any applicable taxes. Another KTM dealer in GA was right ... more »

My 17.5 450 is developing a stress crack under the steering stem, I was thinking about picking up a used frame. Does anyone know if the 250/350 frame interchanges? Part number is different. Thanks!

I have a 165 hour 2017.5 KTM 450SXF. I bought it at 140 hours. It has always made some noise (almost like a chatter) when the clutch is let out, and it goes away when the clutch is pulled in. It has always done this and it isn't getting worse that I ... more »

I'm building an 87 CR 125, looks like the shock was really a weak link. I have to rebuild it anyway, has anyone had any luck with revalving and is it worthwhile? I found the following recommendations from Gorr online - seems pretty straighforward if ... more »

I saw Keefer's test of the 2020.5 KTM 450 Factory Edition and he demonstrated the SKF low drag linkage seals. I'd like to put them on my bike, but every website I've seen doesn't have a listing for the 2020 factory editions. Has anyone done this mod ... more »

New thread KTM 450 Piston Options -- is CP (OEM) worth the extra $100? 1/31/2020 6:29 AM

I just picked up a 17.5 KTM 450SXF-FE, which is running on the original top end at 140 hours (?!?!) I know that sounds crazy, but the bike was original owner / vet rider and I know that he has been religious with oil and air filter changes. So, my first ... more »

I'm about to change the oil in my 2017 YZ 250F shock - the service manual calls for 139.5 psi of nitrogen, but I noticed that Race Tech specs 165 on their website. Seems weird it is so much different. I'm keeping stock valving, I'm thinking I should ... more »

I'm putting an 88 YZ 250 back together and of course the filter cage is missing. The 1988 was a one-year bike for a lot of the parts... and unfortunately the filter cage was one of them. Has anyone found anything else to substitute? Thanks!
