Questions riders ask
Which is faster, the Ninja 400 or R3?
The Ninja 400's extra capacity gives it the edge, most noticeably at motorway speeds and on uphill overtakes.
Which is the better first bike?
Both are excellent. Pick on fit: sit on each, and choose whichever lets you flat-foot at a stop and reach the bars comfortably.
What should I fit first on either bike?
Frame sliders, bar ends and levers. They cost a fraction of the bodywork they protect — see the crash-protection listings on each model's fitment page.
