Two-stroke motorcycles have always been about lightweight power, simplicity, and rideability — but modern emissions requirements and factory tuning have left many riders feeling like their bikes are being held back. That’s where Two Stroke Performance (TSP) comes in.
Founded in Australia, Two Stroke Performance is a rider-driven engineering company focused on one thing: making modern two-stroke engines run the way riders know they should. TSP develops purpose-built performance solutions that improve throttle response, power delivery, and overall rideability without compromising reliability.
The TSP Philosophy: Fix What the Factory Had to Compromise
Modern two-stroke bikes — especially TPI and TBI models — are designed to meet strict global emissions standards. While this keeps manufacturers compliant, it often results in:
- Soft or delayed throttle response
- Lean fueling at low and mid RPM
- Inconsistent power delivery
- Stalling or flame-outs in technical terrain
Two Stroke Performance was created to address these exact issues. Rather than chasing peak horsepower numbers, TSP focuses on real-world performance — smoother delivery, stronger midrange, and predictable throttle control that makes bikes easier and more fun to ride.
TSP ERM: ECU Reflash Modules That Transform Rideability
The flagship product from Two Stroke Performance is the TSP ERM (ECU Reflash Module).
The ERM is designed to optimize factory ECU mapping by correcting fueling and ignition behavior where stock tuning falls short. The result is a bike that:
- Pulls harder from low RPM
- Delivers smoother, more linear power
- Reduces hesitation and flame-outs
- Feels more responsive in technical riding
Unlike generic “one-size-fits-all” solutions, TSP ERMs are developed specifically for modern two-stroke platforms and riding conditions, making them one of the most effective upgrades available for KTM, Husqvarna, and GasGas two-stroke models.

Additional Two Stroke Performance Products
Beyond the ERM, Two Stroke Performance offers complementary components designed to work together as a system, including:
- Performance cylinder heads & inserts
- Power valve covers and engine components
- Fueling and airflow optimization parts
Each product is engineered to improve efficiency, combustion quality, and throttle response — not just dyno numbers.
When combined, these upgrades help riders unlock the true character of their two-stroke engine while maintaining reliability for trail, enduro, and race use.
Why Riders Trust Two Stroke Performance
TSP products are developed and tested by riders who understand demanding conditions — from tight technical terrain to long, high-load rides. Their Australian roots reflect a culture of hard riding, mechanical understanding, and practical performance gains rather than marketing hype.
That’s why Two Stroke Performance has become a trusted name among riders looking to fix common stock issues and get the most out of their modern two-stroke bikes.
