P108 RIDE REVIEW I 2025 BETA RR X-PRO 300 TWO-STROKE & 390 FOUR-STROKE CAN'T GO WRONG You really can't go wrong with either bike. They are high-per- formance trail bikes that are very raceable, but if you want that competitive edge, you'll want the RR Race editions primarily for their high-spec suspensions. However, the X-Pros are plenty capable of going fast. If you're into the more technical side of off-roading, the 300 is excellent for that because of its agile handling, lightweight, and snappy power delivery, whereas the 390 is great for more "flowy" single- track riding where you can easily maintain your momen - tum and speed. However, the 390 feels noticeably heavier than the 300 and may tire you out a bit more quickly when things get spicy on the trail. If you're a four-stroke rider considering switching to the dark side, the 300 is the way to go, and vice versa if you're a two-stroke fan. Either way, you can't go wrong with either one.
