Livio Bolis riding a special Tony Kart, designed and built by Antonio Bosio, powered by a 100cc rotary valve Parilla engine. 133 mph speed record, Monza Circuit 1965... where did he get tires that small that were able to stand up to 133 mph?
The Europeans were light years ahead of the US in terms of 2-stroke kart motor development. The Parilla engines are a work of art! The cases, casting and machining are exceptional. Coming from air-cooled motorcycle engine background, Parilla, figured that they'd drop the fan cooling and use tuned exhaust pipes to maximize performance. The US karts didn't pick up on tuned pipes until much later.
You'll note the placement of the engine in the slipstream because it wasn't industrial fan cooled engine like the McCulloch, West Bends and Power Products. In the mid 60's when karting was at it's peak, well built tires by Goodyear, Carlisle, and others were well built enough to withstand those speeds. The Cheng Shens I run now...not so much. The only thing in common would be the durometer this is pre Goodyear sticky tires, they were narrow and hard.
I actually have both a Parilla BA-13 and a Parilla TG-14 that were imported during that time. Not many came over from Italy and not many survived.
thanks for the in depth look at the Parilla! I've only ever come across the name once before, in 2009, https://justacarguy.blogspot.com/2009/02/moto-parilla-1953-54.html and that was simply a pamphlet
