Honda CRF450R road race bike Dyno check

In for a pre-season freshen-up was this tidy little 450 racebike. Built around a Honda CRF450R single cylinder MX engine with a bespoke chassis and Aprilia swingarm, it was campaigned by a father and son team, with the lad doing the riding. We built the engine originally, and now dad’s taken over the riding as his boy’s packed in; he wanted us to run it on the Dyno and check the fuelling before trekking all the way to his next meeting and, as it happens, it was fine.

Ready for action - rare CRF450R racer in for pre-season checkover.
