2010 Tony Dunnel 350 Manx Norton
81mm bore ultra short stroke Manx, one of four to this spec. For sale as my fathers 79 and needs his pension topping up.
Built by Tony Dunnel in 2010, This bike is to a very high specification and is extremely competitive and a proven race winner in the right hands. It’s one of the quickest 350 Manxs and one of the best handling. It has achieved many race wins and podium places including a 3rd at the Isle of Man Pre-TT.
Genuinely ready to go for the 2025 season. The engine has just been completely rebuilt with only one meeting since. The frame was stripped, inspected and re-finished in 2023. The forks, tank and exhaust have just been recently polished and the seat re-upholstered. The bikes sat on a new Conti front tyre and the rear has done 1 race.
Bought by CRMC Chairman, Mark George in 2013 and owned by him until 2018. It was maintained regardless to cost by Stuart Tonge (a selection of receipts for this are in the paperwork). Mark has documented that the bike was ridden previously by Mike Cooper/Andrew Taylor and featured in Classic Racer.
It was bought by my father in 2018 and has been an amazing bike to ride during our ownership. It has always been looked after by us to a very high standard (my father is a time-served aircraft engineer/inspector)
