tom1 Posted November 28, 2008 Report Share Posted November 28, 2008 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, Quote Link to comment Share on other sites More sharing options...
boofont Posted November 28, 2008 Report Share Posted November 28, 2008 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. Quote Link to comment Share on other sites More sharing options...
tom1 Posted November 28, 2008 Author Report Share Posted November 28, 2008 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??

dfwilson Posted November 28, 2008 Report Share Posted November 28, 2008 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.

scorpa3 Posted November 28, 2008 Report Share Posted November 28, 2008 My '05 moves in a similar way. Quote Link to comment Share on other sites More sharing options...
somerset steve Posted November 28, 2008 Report Share Posted November 28, 2008 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.
