The R80/7 Police Special Escort bike.... Think it had 16k miles on it.
55BHP instead of the standard 50bhp, proper factory job, including the very rare higher final drive ratio (can't remember the exact ratio) and matching speedo number.
Bought at the ADT Car Auction in Enfield, they were put through one morning with the commercial vehicles so no other serious bidders were there.
So me and another bloke who used to buy police bikes shared all the bikes on sale. Around £600 each, all low miles.
I kept two and sold four. All went within a week.
I was finally persuaded to sell this one after i was made an offer i couldn't refuse. One of those i should've kept. I've still got YYX 209T somewhere, it might have 20k miles on it by now.
