Just got a new rear tire on the bike. Installed a Maxxis
Desert IT 110/100-18. Been wanting to try one because of the gnarly granite infested trails around here. Downside is weight. It is a very heavy 14.5 lbs! The worn D756 110/100-18 weighed 11.5 lbs. I weighed a new Dunlop
MX51 110/90-18 (made for a 1.85 rim) and it weighed 12.0 lbs.
The original 6 year old tire wore pretty quickly after about six rides of about 25 mi each on the gnarly trades. The rubber was getting a little hard and "chunking" off. Replaced the rim strip and installed a new heavy duty Kenda
Also, had a couple of lightweight Motion Pro
rim locks. The original wheel only had one rim lock installed, although there was an additional hole in the rim with a small rubber plug. Been running two rim locks on my WR250F and it enabled me to ride out of the trails with a flat for about 15 miles without damaging the wheel or tire. Decided to try two rim locks on the 450X since I don't like to carry tire tools and a spare tube. I have a hard enough time changing a tire in my garage with a tire rack and long irons. I can't imagine the hassle of changing a tube on the trail. The sidewalls on the Desert IT Maxxis are very stiff and difficult to flex enough to get a tube out and back in. I usually put the tube in first when a change a tire.
Rear wheel bearings and seals looked and felt good. Packed more grease into the gap between the bearing and seal.
The front tire still looks good, but I may replace it soon. I've been wanting to try the Dunlop MX71 front tire. Also, still need radiator guards.
Still leaning toward getting a set of the black anodized Mohards. I haven't fallen hard yet...
Checked out a couple of 250X's for my girlfriend. One was a "low miles" 2005 for $2500 and was poorly maintained. It had a rusty chain, a dirty air filter, and dirty oil. Another was a beautiful, clean, never trail ridden, and low miles. He wanted $3200. I offered $3000 and he wouldn't take it. My girlfriend continues to enjoy the smooth
ride of the WR250F. We rode some difficult, rough, rocky climbs and she did well on it. She stalled a couple of times but was able to get her feet down, hit the button, feather the clutch, and get back on her pegs.
