Honda CBR600RR (2BL-PC 40) vs Kawasaki Ninja ZX-6R (MY2019)
Honda CBR600RR vs Kawasaki Ninja ZX-6R: one garage spot. Here's what should decide it.
Roll the Honda CBR600RR's throttle open and it doesn't lunge: the engine climbs through the revs in one unbroken line. The Kawasaki Ninja ZX-6R pulls hard the instant it's opened.
So which one do you buy?
Which one's the smarter buy
Depends what you want it for
Neither is the clear better buy for the money.
What makes each one tick
CBR600RR
The CBR600RR comes alive high on the tach, where the four-cylinder spins smooth and keeps building toward a top-end rush that's worth chasing. At corner entry the front tucks in with real precision, and it doesn't get nervous once it's leaned over. The low clip-ons fold you over the tank, which isn't kind on a long street ride. Feedback flows up through the bar.
Ninja ZX-6R
Shorter gearing lets the Ninja ZX-6R find real drive early on a corner exit, and it doesn't make you wait for the motor to wake up. There's no fuss when the stock dampers meet a bump on the street or at a casual track day. Serious racing finds their ceiling. Under trail braking the rear stays settled to the apex.
Nils rode the Ninja ZX-6R in Spain in 2019 (NastyNils Testride).

Comfortable long-distance riding
Neither is a natural fit

There's no real gap on track days, commuting, twisty roads, and running costs. Sit on both and let fit and price decide.

Known problems to check before you buy
CBR600RR
- Valve clearance check required every 15,200 mi (24,000 km) The ZX-6R 636 (2013-2023) requires valve clearance inspection every 15,200 mi (24,000 km) per the Kawasaki periodic maintenance schedule - a normal interval for the class, comparable to the Honda CBR600RR. Because of the shim-under-bucket design, an out-of-spec check means removing the cams to swap shims, and access requires taking off the tank, fairings and seat. Note: Kawasaki halved this interval to 7,600 mi (12,000 km) only on the updated 2024+ ZX-6R.
