| Video Discription | #motocross #dirtbike #twostroke No talking. No description. Just the pure sounds of a hopped up 125 two stroke on track at Milestone in Southern California. We're bringing our R&D Racing KTM back to life for one more round of action before its put to bed. With the KTM 125SX and Husky TC125 having the same engine, chassis and suspension, we really wanted these bikes to feel distinctly different from each other, which is why we had R&D build the engine and MX-Tech take over the suspension components.When it came time for Dean to build our KTM 125SX, his goal was not to change the powerband’s personality. He wanted to raise the power output everywhere so it would make the same curve on the dyno. He cleaned up the cylinder, cut the head, used a stock piston, added a Bud Racing exhaust pipe and silencer and focused his attention on fine tuning the carburetor. He spent most of his time on the Mikuni carburetor and said he could find a lot of power with the small modifications he did. The R&D engine came to life instantaneously with a twist of the throttle. It offered more of a torquey four-stroke feel off the bottom. The power profile connected the mid and top into a single blended powerband. It was an exciting, powerful engine that was easy to ride. Test riders felt that recovering from mistakes was simple with the added grunt this engine had. Our R&D-modified KTM 125SX engine excelled on tight tracks, as they really highlighted its torquey feel. On the other hand, on faster tracks, every tester thought the power output was increased over stock and revved further. The suspension held up extremely well. It was more tailored to our faster riders and bigger jumps; however, it wasn’t lacking in forgiveness in rough chop. We felt the National shock was a trade-off with the WP shock. Where the National shock was good, the WP wasn’t and vice versa. Every tester was surprised how well this small company’s aftermarket shock worked. Overall, the MXA test riders, of all skill levels, loved this bike. It did everything well; however, our lighter riders felt the suspension was on the stiff side.
