So I recently got this old 1986 WR400. The tires were crap so on goes some Motoz. remove the wheel go to remove the... where the heck is the rim lock? Look at the front and same thing. What the heck? Pull the tires off and find this... these are all the way around the rim about 4 inches apart. Rim pins is what motosportz Mike told me. interesting. I guess this was for quick change ISDE stuff. Seems to work well the old tires have pin marks in them and i see no way the tire could ever slide. Did not make changing them different or harder. Anyway just thought i would share as i have never seen anything like this. Kinda a cool idea. Wonder why it is not used now in this era of light weight? BTW these wheels are made in Norway, look tough and have a crazy three cross rear wheel lacing for the spokes.
Never seen that before. Wonder why we don't fine it on more rims. Do you think it would be beneficial if you got a flat? I mean besides making it easier not to mess with a rim lock when changing. I think it would only work with psi to help out.
I have the same thing on my 1980 CR 390 Restoration ( using 18 " rear wheel off of an 83 XC ). Keeps the tire from spinning in the rim , especially on the bigger two strokes. Note that most of the rear wheels of this era also have two rear rim locks. Good tough wheels that are light weight. Very easy to strip and re-anodize. If buying off of ebay make sure that they do not have cracks radiating out to the edge of the rim... seems to be the most common failure on these rims. T
Hey I have not seen that before, interesting concept-thanks for showing. more than one way to skin a cat huh!!
LOL... Ok you guys are making me feel old..... Yes those are rim pins that we use to use back in the 70's and 80's. Mostly for ISDE tire changes. They took the place of the rim locks. They worked great for keeping the tire from spinning on the rim until you got a flat. Once you lost pressure in the tube it no longer keep the tire pushed out against the pins and then the rim would just spin inside the tire. Then you would have to stop and pull out you over-sized zip tyes to put around the tire and rim to get somewhere to change your tube. Then to help speed up the repair we would install a "bologna" tube. Bet you never heard of one of those either did you?
I remember those bologna tubes,you didn't have to take the tire off the bike, just break one side off the rim and stuff it in and inflate and go.
Yes that's what I was thinking. To bad they didn't work better. I bet it would be OK if you were running the Nuetech Tubliss Core System.
