2020 KTM 150 XC-W TPI

Chaparral Motorsports
May 20, 2019
Last Updated: August 28, 2020

"XC" means cross-country. "W" represents its wide-ratio transmission. "KTM" stands for winning. This nimble, lightweight, extreme terrain master is all new for 2020 and now proudly features the "TPI" (transfer port injection) letters next to its name. This means that there is no longer a need for re-jetting or mixing fuel, making this race-ready machine even simpler to ride and work on. Already recognized for its supreme agility, the new KTM 150 XC-W TPI benefits from a brand-new frame with improved flex characteristics that, together with a list of refinements including new bodywork and updated suspension, helps elevate rider and machine to incredible new levels of performance.

2020 KTM 150 XC-W TPI Highlights

NEW 143.99 cc 2-stroke engine fitted with a patented TPI fuel injection system for perfect fueling at any altitude, no premixing and reduced fuel consumption while still living up to the standard of a KTM 2-stroke.
NEW cylinder with two injectors placed in the rear transfer ports for excellent downstream atomization of fuel and new exhaust port timing with CNC machined edge for improved bottom-end power and performance across the rpm range.
NEW cylinder head with optimized combustion chamber and new water temperature sensor.
EMS featuring a new ECU controlling ignition timing and fuel based on information from sensors reading intake air pressure, throttle position, water temperature and ambient air pressure from a new additional sensor that improves altitude compensation.
An optional map select switch allows the rider to select an alternate map, providing a sportier power delivery, while the standard map is set for smoother and more tractable offroad characteristics.
NEW 39 mm throttle body by Dell'Orto with reworked idle and cold start systems for better adjustability of idle speed and cold start enrichment.
Electronic oil pump feeds oil from the 700 cc oil tank to the intake to ensure a perfect fuel-oil mix under any condition while reducing smoking by 50% and providing up to 5 tanks of fuel.
NEW graphics for a READY TO RACE appearance.
