First Impressions: 2017 KTM 250 SX - More Motocross Videos

In 2016, KTM went all-in and replaced nearly ever model in the Motocross range... Except for their 250 SX two-stroke. Now, one year later, KTM pulled the trigger and released an all new 250 smoker for 2017. Was the wait worth it? Click play to find out.

My opinion was that they were good, but not exceptional. It was a near perfectly groomed Glen Helen, with few bikes on the course so I would't consider it a true test of the performance of the fork on a very rough track. Having said that, they did work well, without much harshness over the small chop, while staying stiff enough to take heavy braking into corners. A little bit of harshness did creep in late in the day under braking as the bumps got a little bit bigger, but that could be improved with either air pressure or valving. Overall I felt they had a good starting platform that could be dialed in for a wide range of rider abilities and riding styles. One side note: I don't feel that fork action is quite as critical on a two-stroke as compared to a four stroke because the two-stroke lacks the heavy pitching of the four-stroke and likes to be steered with the rear end a bit more.

How does the engine compare to last year? More across the range or mid to top? Will it pull a stock 450?

It's a bit more broad across the board I feel. Definitely more rideable. It's still not going to pull a 450, I felt it was still spinning the rear wheel at times, where a 450's torque and track-ability pushes forward harder. In equally capable hands the 450 is still going to produce a faster lap time, but man that 250 is a blast!

Solid information, sign me up. I'll need two Vital front fender decal's and a large fww. Thanks ML and RB.

I may just be some measly peasant, but do you reckon we could occasionally get write ups with these videos? I'd love to watch every video but they chew the mobile data pretty quick
