OSSA gearbox

Not vintage in the slightest. But I have a customer’s 2012 OSSA here that was stuck in gear. (I suspect ‘ham footing’ it.)
Here are a couple of pictures. It is a really neat setup- cassette gearbox, crankshaft comes out the other side. Crankcase is 1 piece, cylinder toward the back- exhaust out the back. Fuel injected (2-stroke).
If I recall, it weighs about 35lbs complete. (I weighed mine).

it is sitting on the clutch housing. It took me an hour to have it on the bench.

That's a beauty. What does the whole bike weigh?
Is the Trials meet still on at Marymont?

Isn't the Ahrma Trials still on at LeMay Marymont? I see they cancelled the swap meet but say the trials is still a go.
