Does anyone have a recommendation for an insurance broker, specifically for a 19 year old?
All depends on circumstances, but many (10, to be precise) years ago Yamaha Link did me a good deal on insurance (aged 20, 20k miles / year commuting, 1 year NCB), so you could try your bike's manufacturers scheme.
Try H and R. They just gave the best quote by far for my 17 y/o on the NSR125RR with 1 years NCD (approx £650 TPFT) -- Dan L (Oldbloke) My NEW bike 1996 Kawasaki ZR1100 Zephyr My old Bike 2000 Honda CB500 (for sale) M'boy's current bike 1990 Suzuki TS50X (Heavily fortified) M'boys NEW bike 2003 Honda NSR125R BOTAFOT #140, DIAABTCOD #26
I used motorcycle direct when I had one of those (and was a similar age). I will warn you though, for my first year the figure on the paper was ?2963 FC (although thanks to a deal I didn't pay that), but the renewal was still over ?1K for a 19yo in 1999.
