Yep, Mike "the Bike" Hailwood thrashed the competition with his Honda RC 166 GP bike winning a world championship in both '66 and '67. The bike featured a 250 cc straight 6 engine with dual-overhead camshafts and six carbs all nested together in a tiny amount of space.
Now Tamiya is offering a high detail version in 1/12. The bike will be offered as a plastic kit and no less than FOUR detail-up items available seperately. It looks like the folks at Tamiya are really trying to do this one right. The chain looks incredible. Here are some links to the HLJ site:
