The JJCobas PVH21 was built in 1991, with a double-beam aluminum frame and was powered
by a Honda RS250 V2 engine. Antonio followed the same concept as in the series with Rotax
engines. This one, though, didn’t have suspension’s anchors in the engine and had Honda
mechanics with a single crankshaft.
