In its five year production run, the 350 Twin was the recipient of contstant improvements. One of teh most notable was teh introduction of electronic ignition in the spring of 1972. This upgrade improved the reliability of the motorcycle. The pushrod, 4-stroke twin cilinder engine still generated 27 HP, and for the boy-racer, a fairing that resembled a competition setup was available, but it did have a headlight to keep it stree legal. There was even a police version of this model, complete with crash bars, windscreen, pannier bags, siren and direction indicators.
