At the SCTA/BNI Bonneville Speed Week this past August, they set a total of 4 new world speed records. In this feature, we take a closer look at 5 racing bikes from Tweakers Racing, including the two record-breaking machines, and Yasui traces his 4-year journey to becoming the world’s fastest.
From the 1950s, while competing in events such as the Isle of Man TT and the World GP, Honda released high-performance commercial models that would lead the next generation of motorcycles. The parallel two-cylinder machines Honda released in the ‘60s are especially loved by enthusiasts. Designed to compete with the British bikes that dominated the motorcycle market, these two-cylinder machines included ambitious and innovative engineering. In this special feature, we focus on the parallel twins produced by Honda up to the eve of the CB750's release, including a Yoshimura-Honda CB72 discovered in the US that maniacs will drool over.
