Suzuki GSX250R 0-60 mph in 8.59 seconds
The Suzuki GSX250R was released in 2017 to compete in the ultra-competitive smaller capacity sportbike learner category. Suzuki were a little slow to introduce a new bike to this class with competitors such as Honda with their CBR250R and Kawasaki’s Ninja 250 having released new bikes before: in 2011 and 2104 respectively.
Well Suzuki did have the naked Inazuma 250 but that was never really a competitor to any of the full fairing offerings from Honda and Kawasaki.
The GSX250R is primarily focused at Asian markets but has been sold all around the world as it makes a great sporty commuter and learner bike. It’s a great looking motorcycle powered by a parallel 2 248cc engine based off of the naked Inazuma mentioned earlier.
Suzuki claimed that they designed the engine for low and mid-range and I’ll take their word for it as engine poke does seem to fizzle out past 8000 rpm unlike other 250 cc parallel twins but does offer reasonable zip below.
It is a smooth engine though, and definitely smooth for a parallel twin, which Suzuki claim is down to their cam profile design.
The little Suzuki GSX250R does have its work cut out. The 250 cc plus entry level small capacity class is remarkably diverse with many motorcycles that compete from engine sizes up-to 500 cc.
Suzuki’s engine being at the lower end size-wise, means that it will likely be one of the slowest in-class, and perhaps even slower than the Ninja 250 and CBR250R which are two of the other 250cc competitors in the class.

The little Suzuki only makes 21 horsepower at the wheels. This figure is at the bottom end of the Japanese 250 class and is eclipsed by some of the slightly lager capacity bikes such as the Ninja 300 and CBR300R. They have more cc so not too fair to compare with our 248cc GSX250R.
If we look at the little Suzuki in isolation it has a respectable amount of low end power and torque that pulls smoothly from 2000 rpm and offering a little and slightly noticeable kick 4500 rpm where it builds power up-to around 8000 rpm, and then starts to tail-off approaching 9000 rpm and falls off of a cliff after that.
There is really not much point revving beyond 8000-85000 rpm as you will make slower progress but you do have to work the gears. Honda’s single cylinder CBR250R actually makes more top-end power than the twin cylinder Suzuki

In terms of numbers, you need 3 gear changes to hit the magic 0-60 mph which is achieved in a respectable 8.59 seconds for the GSX250R. A more relevant and meaningful time for where this bike will live would be the 0-30 mph time, which is 2.67 seconds, and is like many other vehicles that will get to 60 mph 3 seconds faster.
If you push-on, the GSX250R will get the quarter mile done in 16.70 @ 76 mph and onto a top speed of 85.5 mph achieved in a racer tuck and with chin on the tank. The top speed is actually rev limited to 85.5 mph as we are hitting the rev limiter. With slightly longer gearing you might be able to hit a few extra mph.
Changing gears at the right rpm is key to achieve the best times with the ideal shift point being around the 8-8500 rpm point. While the GSX250R will happily do highway miles, if the traffic is moving faster than legal speeds, be prepared to plan your overtake carefully but even then if traffic is above 80 mph you better stay out of the overtaking lanes.
As the motorcycle is only 248 cc and has only 21 hp at the wheels, the performance difference between a heavy and a light rider will be quite large. To achieve similar acceleration times as we have you’d need favourable conditions and a rider weight 80 kg or under.
If you want a ‘fast’ 250 this is not the bike for you though saying that it is faster to 60 mph than a current entry level Volkswagen Golf. If fast is important to you but you are still a learner you’d be better off with a Ninja 250, Ninja 300 or 400 for more straight-line thrills but similar comfort and practicality.
