I think power wise it's perfect. There's enough if you want to take it on the hwy you can. I've never felt it was to much power for me. If you get up on the gas fast it won't feel like you are hanging on for dear life trying not to fly off the back. Hope this helps.I have the same criteria. While I want something i won’t outgrow quickly, I don’t want to feel that there’s more power than I can handle either.
You ended up with the better bike. I've ridden the CB500 quite a bit and can tell you it's heavy and a bit boring compared to the Ninja. It doesn't rev out like the Ninja, redline is at 9,000 RPM. The Ninja has a much better power to weight ratio and is the more fun bike of the two to ride IMO.My first bike; the motorcycle saftey course being the only other time I was on a bike. Was set to buy a 18 CBR500R when they were on clearance sale back in march but life happened. Another dealer was having a Fathers Day sale and ninja 400's were marked way down; went in to check them out saw the Z400 for the first time. It was a tough decision because the ninja 400 was actually cheaper than the Z but told them if they could get me a green one Id take it.
I'm happy with my purchase. Ive made mistakes on this bike that probably would've been bad on a bigger heavier bike.
