I know he has not had any accidents on bikes so i would say he must be safe as far as anyone can be on a bike. The dealer will not discount this model at all. Not sure if they sell well but there are a lot of pre-registered ones on the market around the country. All with just a few miles.
This is like the time i bought a Thunderbird sport registered in Leicester to a Triumph employee but still on a pallet in Exeter. It was 1 year old unused with a list price of 7400 pounds and i paid 4600 pounds. Bridge garage had a warehouse full of pre reg bikes in stock but not in the showrooms. Currently, Taunton Triumph have a lot of pre reg new style Rocket 111s in stock being sold at a lower price. Victim of the lockdown i suppose.
My large bikes are still on Sorn until we get permission to ride to faraway places.
