November 28, 200817 yr my old man's just bought an 05 sy250 2t and the front disc seems to be loose on the hub (when you grab the fron brake you can feel and see the hub and wheel move about an inch even though the disc is locked) bolts seem tight enough and the right length, the shop it came from said ths is normal and they all do it, but on my little ty125 it doesn't! anyone know if that is the case or is something up cheers,
November 28, 200817 yr There is a bit of movement, it's known as a 'floating disc', an inch sounds too much though, should be a couple of mm at most.
November 28, 200817 yr Author Blimey! Trials bikes have floating discs! i thought that was only big road bikes and crossers!!! shows how much i know! lol. the wheel moves about an inch the disc itself moves about 5 mm i'd say. would he disc be worn or something is it the cup wsshers that need repacing??
November 28, 200817 yr Sounds like the front wheel bearings may be trash. The front disc is attached with half thimbles which are secured to the hub with socket head screws. These screws can come loose. If they do come loose they will eventually stick out far enough to contact something and the the fromt wheel will stop instantly. Cheers DFW
November 28, 200817 yr Author its not the wheel baerings i've checked that, its definatly the disc moving on the hub
November 28, 200817 yr I fitted 1999 Gas Gas 249 front disk on my 03 Scorpa. The scorpa disk has movement on the hub, it tends to be a bit off putting when doing tight turns. The GasGas front disk fits straight onto the scorpa wheel hub, bolts on tight, giving no movement.
February 13, 201214 yr Instead of opening a new thread il thought il post here. My front disc moves a little bit on my beta and I know this is normal but does the rear supposes to do it as well. My rear were loose so I tighten then up and don't move anyone more l, should I slacken the off a little bit.
