Two Stroke Performance Engine Tuning

23/09/2026

We’re heading to the 2026 Australian Junior Motocross Championship next week! 🏁🔥

Most of the TSP staff will be there for the full week, getting behind our riders and soaking up what’s set to be an awesome week of racing.

We’ll have some TSP merch and a small amount of emergency stock available for purchase, but our main reason for being there is supporting the riders, helping out where we can, and enjoying the racing!

If you’re heading to the event, you're welcome to come find the TSP crew say hello! We’re looking forward to seeing plenty of familiar faces trackside! 🤘

▶ Please note: This will mean we're running on very limited numbers at TSP HQ for the week due to most of the staff being at the event. Expect small delays in order shipments, email replies and very limited phone support.

💥 Beta 350RX 2T 2026-on TSP Power kit Announcement! 💥

Our Beta 350RX package delivers major performance gains across the whole RPM range, with a massive 8HP over the standard peak power! This is an incredible 16.5% increase at peak power, absolutely transforming the power over the stock engine setup! This bike now performs how we believe it should have from the factory.

This result is achieved by running the following products:

- TSP Cylinder head & Insert with a 1.5mm thick base-gasket to suit
- TSP Base-line jetting specifications
- TSP Recommended Power-valve settings
- Optional: TSP offset flywheel key

Instructions on how to set up the powervalve actuator arm to suit the raised cylinder setup will be included.

This setup will also improve the throttle response/smoothness, with reduced risk of detonation.

You can check out our listing for more detail here: https://www.twostrokeperformance.com.au/product/beta-350-rx-2026-on-models-tsp-billet-head/

Available for purchase now directly through our website, or very-soon via your local TSP Reseller.

💥 Yamaha YZ65 2018-on TSP Power kit Announcement! 💥

Delivers major performance gains across the full RPM range, including over 2HP more than stock from 8,500RPM, with some areas showing gains of up to 3HP! We spent many track days with high level riders testing and hundreds of dyno runs to get these results. This kit absolutely rips over the standard setup, and we've had great success locally to now bring it to the public!

This package is championship level proven, and comes with the following components;

- Complete TSP Billet Head anodised in factory-look bronze & insert with required cylinder head o-rings
- TSP CDI unit programmed with TSP race map
- Recommended jetting specifications to suit
- DOMA cone pipe + silencer

Perfect time to get your YZ65 dialled in before the Aussie titles!
