Was it the Britten? https://upload.wikimedia.org/wikipedia/commons/4/40/Britten_V1000.jpgSome race motorcycle designer tried a meredith style cooling system about 25 years ago. The bike had many interesting features. I never saw it again.
No, not Britten, James Parker with the RATZ which was a Rational Advanced Design Development (RADD) using a TZ 250 Yamaha race engine. Oct 1995 in Sport Rider, though I am sure it is in other magazines. The air cooling ducts went from the front of the fairing (near the headlights) to the under-seat radiator. The heated coolant air went into the rear wheel well. I think the text of the original article referenced Meredith, but it seems to be missing some key elements. The RADD/RATZ ideas seem to be in abeyance and the coolant ideas gone...Was it the Britten? https://upload.wikimedia.org/wikipedia/commons/4/40/Britten_V1000.jpg
The designer of this John Britten died at an early age.He would have made a great airplane designer.
The Britten design from 1987 had raced at Daytona in 1990 and 1991 and Assen in 1992 so was possibly before Parker.I don't know who was first or how much each learned from the other
