I own one. '78 twin shock. Totally original and in showroom condition. It's such a beast, yet such a pussy cat. Eerily smooth, with virtually no vibration, really comfortable, gob smacking looks, enough character to keep you intrigued forever. I feel as if mine's alive - like it's a crazy relation with a bad attitude but good manners that you just love to catch up with every time. 10/10. If you ever get the chance, buy one, and if you own one, never sell it!
