IS THE 2018 KTM 125SX BETTER THAN THE 2017 KTM 125SX? Yes! Small changes were made to the orange racer for 2018. These are the words from Motocross Action "Race Test" The KTM 125SX has claimed the mantle as the greatest 125cc machine on the showroom floors. For 2018, KTM’s engineers have made updates to the carb, suspension and head stays. The entire KTM SX lineup got an orange frame and a new look. This one has a "FMF" pipe on it too. Fuel mixture. Last year the 125SX called for a lean 60:1 fuel/oil mixture. For 2018 it has been changed back to the normal standard of 40:1
With the pre-mix ratio changed for 2018, the jetting has been changed as well. For 2018, the 125SX’s Mikuni TMX 38mm carb has a different needle. Although the main jet remained 480, the pilot was upsized from a 25 to a 35.
The 125SX got the update to its WP AER air forks. There is a new piston, air seal and updated valving.
The head stays are now made out of aluminum instead of steel.
The frame is has changed from black to orange.
The valving has been revised to work with the new fork valving. This is a 125cc with all the current technology built into it. MXA test riders love everything about this bike. Looking for a 125 Two stroke bike, This one has it going on!!! Stop in, or give us a call!!! Sunday is coming up, It is ready to go to the track!!!
