ABOUT THE 2019 KTM SX 250

2019 KTM SX 250 got the same chassis changes as the rest of the KTM motocross fleet. That includes the more rigid frame, updated bodywork and smaller airbox. Changes that were proprietary to the 2019 KTM 250SX were limited to updated jetting for the 38mm flat-slide Mikuni carburetor, suspension settings, a redesigned exhaust and reworked water-pump casting. \

PRODUCT DESCRIPTION

YZ250 two-stroke. We don’t fully understand the price increase, given that over the past two model years the changes don’t seem to justify the 6-percent upcharge. The price tag makes the $7399 YZ250 more attractive.
Compared to the 2017–’18 model, it runs more like an offroad bike than a motocross bike. The engineers at KTM tamped down the power on the entire 2019 KTM fleet by making the airbox smaller and more restrictive. Why? We don’t even think KTM knows the answer to that. Most likely, the engineers found something on the dyno that didn’t transfer to the track. That puts the onus for the powerband problems on the KTM test riders.

We admit that the 2017 and 2018 KTM 250SX powerplant was at times overly aggressive. The previous KTM 250SX powerband exploded in the midrange and signed off fast on top, leaving test riders wanting more breadth. In 2019, the restrictive airbox not only mutes the aggressive feeling but doesn’t aid in connecting the rest of the powerband together. 

Don’t get us wrong; this is still a fast 250cc two-stroke. It just isn’t as fast as it was last year. With the choked-up low-to-mid, the power doesn’t build quickly enough, which makes our testers abuse the clutch to get into the meat of the power—and that meat doesn’t last long enough. The 2019 KTM 250SX still signs off early on top but is now very muted on the bottom. That is a recipe for confusion. It is worth noting that slower test riders, especially those who felt that the 2018 KTM 250SX hit too hard, liked the muted power as it was easier to control.
