Most Using Dirt Bike In Sri Lanka

 Honda CRF250R

The Honda CRF250R is Big Red’s four-stroke production motocross bike for the 250F class. It competes annually in Dirt Rider’s 250 four-stroke shootout and received fifth place this year. The machine may have slipped down a rank compared to 2020, but that doesn’t mean it lacks in fun. Take the handling and engine as prime examples that this machine performs well and has a reasonable MSRP.The CRF250R is powered by a 249cc single-cylinder engine that, when measured on our in-house dyno, cranked 39.0 hp at 12,900 rpm and 18.8 pound-feet of torque at 9,500 rpm at the rear wheel. And while it didn’t deliver the most peak power of the group, the CRF250R’s “free-revving engine is one of the characteristics that make it so much fun to ride,” Dirt Rider’s Andrew Oldar reports. “It offers a smooth, linear powerband from bottom to top with no real hit anywhere in the rpm range, all of which contribute to the bike’s ability to get great traction.”

Yamaha YZ250F

First introduced in 1974, the Yamaha YZ250 has stood the test of time. The YZ250 is an ideal bike for a rider who wants a two-stroke motocrosser that is fun to ride and easy to maintain, while rebelling against the modern-day four-strokes. It has a long power delivery, plush KYB suspension, and proven durability. Of the big six manufacturers, Yamaha is one of only three to still offer a 250cc two-stroke motocross bike in 2020 and is the last premix-burning quarter-liter MXer from Japan. It’s also the only bike in its category to come with a cable-actuated clutch.he Yamaha YZ250 hasn’t changed much since 2006, but it has remained as a competitive package in recent years, as evidenced by a comparison test conducted by our dirt-only sister publication, Dirt Rider, between the YZ250 and KTM 250 SX.


KTM 250SX

As winner of Dirt Rider’s Best Motocross Shootout for two consecutive years (2019 and 2020), the KTM 250 SX-F was bound to stoke the fires of competition, and so it did. While the Yamaha YZ250F took first place for 2021′s shootout, the KTM still followed closely behind taking second. Its strong and fast engine, nimble handling, tunable suspension, light weight, and excellent brakes continue to serve this machine well. Its high-rpm powerband makes it a suitable ride for intermediate and pro-level riders.

The KTM 250 SX-F is powered by the same liquid-cooled, DOHC, 250cc four-stroke engine as its counterpart, the Husqvarna FC 250. In measuring the machine’s rear wheel power figures for the five-bike comparison, the SX-F produced the highest horsepower figures and second highest torque numbers: 41.1 hp at 13,700 rpm and 19.1 pound-feet of torque at 9,100 rpm.While the engine doesn’t produce the strongest low-end power, it excels in seemingly endless top-end pull. Contributing to its low-end power performance and rpm recovery characteristics is the bike’s long gear ratios.

Kawasaki KX250X

The Kawasaki KX250 is a four-stroke motocross bike that takes after its bigger stablemate, the KX450, in chassis, EFI mapping system, hydraulic clutch, and front brake setup for 2021. The smaller KX also sees a multitude of other improvements, making it one of the most revamped models this year.As a well-rounded machine in stock form, the 2021 Kawasaki KX250 offers a nice mix of trickled-down improvements and a higher revving four-stroke 250cc engine. This model ranked fourth among the other 250 four-strokes in Dirt Rider’s 2021 250 Four-Stroke Motocross Bike Comparison Test where it was praised for its neutral-handling chassis, great ergos, competitive top-end power, and smooth clutch pull. The KX250 is powered by the 249cc, four-stroke, DOHC liquid-cooled engine. This dirt bike recorded 39.60 hp at 13,220 rpm and 18.38 pound-feet at 9,440 rpm on our rear-wheel in-house dyno.

The engine’s internal components have seen quite a few updates, but characteristics are very similar to what was seen in 2020. Now it has a little more over-rev because of the increased rev limit, and power delivery is better if you keep the revs up. The Dirt Rider 250 four-stroke comparison test did find that the engine characteristics and power delivery did still leave a bit to be desired though.Second gear will be used in most corners. Third is not needed until corner exits and is overall very useful. Fourth only needs to be used on faster straightaways, we reported in our First Ride Review. Further, shifting under load was reasonably easy with only a small amount of clutch lever input needed thanks to the new hydraulic clutch.
