Ariel Square 4 swingarm replica/homage 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. The engine has done altogether approximately 8000 trouble free miles since. It has been further improved and recommissioned by the previous owner after it spent time in a European museum, and most recently 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. It is a practical and useable and fine handling albeit exclusive classic and possibly the best of all worlds Ariel. Super smooth and easy starting. Reluctant sale, genuine reason, as down sizing my classic collection due to age and relocation. Own the Square 4 Ariel should have made. Priced to sell at £13250 given the current market, even though it has been previously valued at £20k. May do deal on sorted Hesketh, particulary a Vampire. Tel 07970 713981 with any questions, this is a straight classified and and I encourage serious enquiries.
