No, not even close, they were complete slugs and complete under achiever, but the later model Exciter II was better. The original Exciter had power, way more than my 400, but no manufacturer back in the day could seem to get the power to the ground. That little free spinning 400 would edge the Exciter, especially out of the hole. Remember the clutching in the Doo's and Yamahas were garbage and the tracks shit. Yamahas 1/4" lug and Doo 16" wide low lug fat tracker really killed horse power. The P85 and 1/2 lug 15" track was the reason Polaris could get a 70hp 500 run 90mph on the right day. The rest, except Cat, couldn't get there.
