Some may wonder why there’s even such a thing as a de-tuning kit when the Kawasaki Z650’s engine is tune to perfection.
That’s because some European countries, like the UK and Italy, places power output limits on certain motorcycle license levels. Say a young rider decides to go for an A2 license at 19 because it is the quickest and most cost effective way to graduate to an unrestricted motorbike license. Before graduating to a full license, A2 holders can only ride on bikes that produce no more than 35 kW or 47bhp. Of note is the lack of torque restriction, so the max torque of 65.7 Nm should remain untouched.
The Kawasaki Z650 exceeds that power limit because its 649cc 4-stroke engine delivers 50.2 kW, meaning a large group of potential A2 customers will have to look elsewhere for their first bike. To remedy this problem, participating Kawasaki dealerships are offering new riders a 35 kW de-tuning kit for free. It’s included in the purchase price and the offer is valid until June 30 of this year. We’re not quite sure if this modification is reversible as there’s no mention of what happens after someone passes the full motorcycle license test.
One can only assume the Z650 can revert to producing 67 bhp @ 8000 rpm.
