The ZZR & KR-1S frames are very similar, I think Kawasaki just retasked the production from KR to ZZR by changing the extruded side rails & internal cross bracing to suit the ZZR.

My little motorcycle party quiz question is what was the most powerful 4-stroke motorcycle by HP for the longest time ? Answer the GPZ/GPX/ZZR/Ninja 250. Rated at 45hp by the factory, for 180bhp/Litre !!!!! They all say what, but it was launched in 1984 (Japan only) and was still in production until the 300 took its place, but still exists in parts of the world as a 250, but based on the 300 engine. It took until around 2005/06 before a litre bike made a claimed 180hp ! So for 20 years the baby Ninja’s were the most powerful engines you could buy.

The 4 cylinder 250’s didn’t make any more power due to Japanese regulations & the 600’s never quite matched the HP per litre on the baby Ninjas until the very late 90’s or early 2000’s but they never surpassed them. . Interesting that the engine tech for these kinds of power levels existed way back in the 80’s.

Interestingly, rumour has it that Kawasaki May be planning to launch a new 250 4-cylinder !!!
