They are also featherweights, with some models under 100kg or 220lb with a full tank of fuel. A few years ago we reviewed the Beta RR125 and it was like riding a mountain bicycle! Despite bogging the engine down repeatedly, I was consistently faster on timed laps than the 250 and 300 two-strokes. Riders who might like the 125? Young riders upgrading to their first full-sized dirt motorbike. Older riders who love the scream of two-strokes but don't want to ride crazy fast for that thrill. And of course, anyone on a budget. These 125s are so much cheaper. You will need to rebuild the engines more often but the savings can be huge. We haven't ridden any of the 150 two-strokes yet, but they do get rave reviews from many riders. You can see in the dyno chart there isn't significantly more maximum power but there's just more horsepower across the low to midrange revs. It's interesting to see the power delivery is so linear nowadays compared to the very peaky two-strokes of yesteryear. Next? The 200 two-strokes. Again, these are often overlooked by many riders which is a shame as they are so much fun to ride. KTM's 200 became a real hit in the late 1990s.

Ditto for the Beta RR200 we reviewed a few years ago. It's interesting to see the 200 models can actually put out less maximum horsepower than 125s. But of course there is way more power in the low to midrange revs which makes them very user-friendly. Our dirt riding tips are great for developing your hard enduro skills.

Similar to the 125s, manufacturers have to price these 200s very competitively because most riders overlook them. Finally the 250 and 300 two-strokes. Our group is into hard enduro so these are our favourite engine sizes. You can see from the dyno chart there is way more grunt and the maximum revs are much lower. Maximum power is usually about the same in most brands, and while the difference looks small at lower revs, the engines do feel very different when riding. In a nutshell? The 300 is the grunt-meister and the preferred size for hard enduro, or everyday riders who prefer to lug their engines instead of rev them. The extra power at lower revs can get less experienced riders into trouble faster though. Some riders say the 300 suits the 'lazy' rider too. The broader range of power does mean less clutch slipping in gnarly terrain and fewer gear changes on faster tracks. The 250? It's lively. It revs up faster. It will be easier and less tiring for less experienced riders. On the flip side, experienced riders who love getting into the powerband will probably find the 250 a more rewarding experience. Some riders claim the 250 is more 'flickable' on tight tracks due to less rotational mass although I have never noticed this myself. The 250s do have less grunt, but the gap is narrowing. For example, one of our guys has the Sherco 250SE with the electronic power valve and we find the grunt is almost comparable to 300s in other brands.
