Merry Christmas one and all. Here's my problem: I was out riding yesterday on my 98 XR400 on fire roads (sand mostly) in South Jersey. My son and I traded bikes (KTM 400EXC) and I found that the KTM was much less squirrely than the XR. You could lose the front end on the XR, and I did a couple of times, though it wasn't bad enough to cause a crash. The KTM felt fully planted, and much more stable. The XR wasn't bad - just not as stable in cornering or over bumps as the KTM. The KTM has fairly new rubber, Kenda trackmaster rear, Kenda 777 enduro front. The XR has D606 Dunlops front and rear, with about 600 miles of mostly offroad on them. The XR also has a Clarke 3.8 gallon tank, which was full at the time. It also has a racetech front suspension, with springs rated for my weight. Anyone got any idea why the XR front end didn't feel as good as the KTM? Front tire pressures were 9 psi in the KTM, 11 psi in the XR, so maybe that had something to do with it? Gas tank? Riding position? Worn tires? Crappy D606s? Thanks in advance.
