Yamaha Aerox 155 is one of the quickest scooters in the segment. It is very powerful and aggressive. It is powered by a 155cc engine which makes 15PS. The Aerox 155 rolls on 14-inch tyres sprung on a telescopic fork and twin shock absorbers. With a 790mm seat height and 126kg kerb weight, it is fairly accessible too. Its ground clearance, though, is a bit low at 145mm. For the braking process, the Aerox employs a 230mm disc up front along with a 130mm drum brake at the rear. All these specs make it a great option for long rides and the ergonomics are pretty good as well.
