Title: Driveline seizing up
Post by: Mick Lee on June 10, 2025, 09:41:38 AM

Hi  everyone

Only had my bike a week or so and no dramas. Went to move bike this morning and found I could not push it forward or back when in neutral position. When engaged into first the bike stalls. HELP please.

Can't pull it onto its centre stand to check...on my own for a few hours.

Any, if only slight, rotation of the wheels? 

Or are the wheels locked as if a brake is "on" firmly?

yep, I had the same trouble with mine. Strip and rebuild the calipers and while you're in there, do the master cylinder as well.

Jammed front brake?? or seized bearings.. Seized bearings is very unlikely though. Check tyre pressures, they dont roll well with a flat tyre.

Undo the bleed valves to release any stored pressure, it doesnt take much to lock the brakes on.

if it's full of junk like mine were, releasing pressure didn't help. the pistons were seized in the caliper.  I ended up removing the front calipers to roll the bike.
Now in fairness, mine had sat under a tarp in Brisbane for 10 years before I got it. Everything was absolutely clogged up and needed maintenance.
