Hi martin_csr, yes, Shannons are highly respected here in Oz.
They are the No 1 go to for insurance for vintage, classic, modified, unusual, rare vehicles and motorcycles.
No other insurance company can match their policies, believe me ,I've looked.
Shannons have been running auctions for many years and are highly reputable , attracting the very best selection of vintage, classic and more stock.
I was very surprised to see that description of the bike concerned, the only explanation I can think of is maybe they have a "new guy" writing the blurb and hopefully he/she will get better at it.
All my vehicles are insured by Shannons and when my z650 build is finished it will be too.
Harley insured by them.
