Berty,
I haven't got a clue what the insurance would think about it. You're better asking them.
If you are tempted to go metal be aware there can be a lot of condensation in the winter months, I.e. 11 months of the year.
It's not insurmountable but it can mean extra work to make it suitable bike storage.
Upt.

I'm completely ambidextrous.  I can do bugger all with both hands.
I'll get me coat.....

Anybody had one of these or similar?

Wonder if it would count as "garaged" for insurance purposes?

I have been doing a few hours extra at work, due to the pallet network that we use going bust. So we have found another network to do our odd pallets ( full loads go direct ) any how the jobs were all picked and the shunts were all done. So my boss said you have been staying late quite a bit ( they do not pay overtime) so why don’t you go early the sun is out and go out on your bike.
Well I didn’t need telling twice 🤣.
So I had went out for a couple of hours around some lovely B roads and A few A roads, stopping off at The museum of power in Langford near Maldon in Essex for a picture or 2. Riding though some of the villages the kids were getting off of the school buses and they were gesturing with there hands to rev the Engine 🤣🤣 which I duly did as the Harley sounds great on the overrun 🤣
In the pictures you will see a Heron which I thought it was one of the plastic ones until it flew off ( second picture it has gone )

The GW250 service manual says 5.5Nm so go with that, it's the same engine with the same part codes and the same nut. Looking at parts sites will confirm where parts are different but I think you're pretty safe taking the GW250 manual as gospel for anything drivetrain related.
