Suzuki’s GSX-R400 is easily mistakable for its larger brother the 750 with its distinctive slingshot looks and aluminum frame. Not as sought after as the other Japanese 400cc imports, but that keep prices low and means you can grab a bargain. Handling is excellent handling, but the engine requires a thrashing as its all revs, but it’s still rewarding to ride fast.

The Suzuki GSX-R400 feels very similar to its larger brother – but shrunk down. Its tiny pegs are high and are a nightmare on the road but they make sense on the track. However, you need to play around with the suspension. On most models the rear is too soft and causes under steer. But once set-up, despite its old-fashioned-looking frame, it’s a little track weapon

Some versions of the Suzuki GSX-R400 were speed restricted to just over 110mph, however, once de-restricted, the engine loves to rev all the way to an 15,000 rpm redline. Real back wheel figures can be as much as 60bhp which makes the GSX-R no slouch but don’t expect anything below 6,000rpm.

The Suzuki GSX-R400’s bodywork can soon appear shabby, especially if it’s seen a few British winters and been trashed by excitable youngsters. Clutches can take a real hammering, also, but the engine seems reliable, just like every GSX-R.

The Suzuki GSX-R400’s upside-down 41mm front forks are adjustable for pre-load only but the rear is fully adjustable. Nissin front brake calipers and that distinctive looking aluminium frame give it the appearance of its bigger brother. Overall, it’s comparable to the other Japanese four-cylinder 400s.
