Twin overhead cams, four cylinder, four stroke with ram air engine cooling. It had four Amal carburetors.
It couldn't compete against the TZ350's and especially not when noise regulations restricted the previously open exhaust pipes. I suspect this is one of the few picture in existence. Tony Rutter once test rode it at Wellesbourne on a very cold day in about 1976. There is a further description here: http://www.gracesguide.co.uk/wiki/KRM However, it was never raced at Brands Hatch. Originally it had wire wheels, these were soon replace with mag alloys. The Silver Streak tag was dropped. By 1978 the project was shelved. We mostly tested it at either Brands Hatch or Snetterton. Oh yes I was one of the test riders....
