Ariel Square 4 swingarm replica of the factory prototype but with every upgrade of the time and since to produce the bike Ariel would have made in the late 60s. This is a late model alloy 1000cc Square 4 completely rebuilt and uprated to Sealey spec. It has been further improved and recommissioned by the previous owner and myself, having owned it for the past two years. All the info you need to read is in the photos. I have a huge file including the original copies of magazines featuring the bike. Lately I have fitted a JAAG thermostatic inline switch to replace the previous oil cooler bypass to ensure optimum operating temperature at all times, reset the SU carb and fettled the chassis. It is set up with a high output oil pump, spin on filter and runs on high spec multigrade. Stunning bike and a much better option than buying the Mk3/ 4 swingarm prototype from the National Motorcycle Museum. Tel the details belowIt is a practical and useable Square Four, fine handling and braking with a super smooth uprated engine, albeit a unique exclusive classic it is possibly the best of all worlds and all things Ariel. Reluctant sale, genuine reason. Own the Square 4 Ariel should have made in the late 60s. If you're genuinely interested, phone for a chat. £12995 ovno tel the details below
