Description
At D-Spec Motosport, we develop real-world performance solutions — tested both on the dyno and on the track, in multiple riding and racing conditions. We’re not chasing big peak horsepower numbers just to make the graph look good. What matters is throttle response, power delivery, traction, and overall efficiency across the full rev range. Real gains happen in the 97% of the time you’re not wide open — and that’s where we focus.
Our kits are complete, easy to install, and track-proven.
Performance packages that deliver.
🟢 Stage 1 – Straightforward gains, instant impact
Custom D-Spec mapping on GET SX1-PRO ECU + outerwears pre-filter
🔥 Stage 2 – A winning setup, ready to perform
Includes high-performance RP race exhaust system to unlock engine flow
⛽ Stage 2+ – Built for race fuel power, calibrated to perfection
Dual maps: one for pump fuel, one for race fuel
🏆 Stage 3 – The ultimate setup, dyno-built and race-validated
Full package with dual-injector throttle body and advanced mapping
At D-Spec Motosport, we don’t sell hype — we design, test, and deliver results. Our kits are simple, effective, and built to transform your bike without compromising reliability.
This Austrian 250 platform (250 SX-F / FC250 / MC250F) is already a beast in stock trim. That doesn’t mean we can’t improve it.
We spent a lot of R&D on that bike and we have results to demonstrate it. We have many levels of performance available for this platform.
In stock form, it will pull smoothly till the rev limiter if you are willing to hold it wide-open that long. We came up with solutions that make the engine go quicker to the rev limiter with enhanced torque feeling. All of that with even MORE top-end scream.
With our proven strategies — custom mapping, RP exhaust systems, dual injector throttle body — we take it to the next level.
All our products are tested in real conditions, with measurable results. You just need to pick your level.
🏁 National-level package
A full Stage 3 engine build, with internal mods proven in championship racing.
📌 Delivers smooth, reliable power and gets you out front with Pro MX holeshot-ready pull.
Tested Exhaust Systems
At D-Spec, we’ve tested several options — but the RP Race system remains our top choice for balanced performance:
✔ Power spread evenly across the full RPM range
✔ Sharp throttle response with strong overrev
✔ Clean, race-inspired sound
Quick comparison:
• HGS – Good low-end torque, signs off early
• Akrapovic – Smooth bottom end, impressive overrev
• FMF – Good low-end torque, good top-end stretch
• OEM – Great low-end torque, excellent performance-to-cost ratio
💡 No exhaust performs perfectly on its own — it’s the right match with the mapping that makes all the difference.
Airbox & Filters
• Vented airbox lid recommended (except in very wet conditions)
• Outerwears – Primary filtration + water resistance
• 2-stroke air cage – Effective budget option under $20 (Part #: A46006026033)
• Twin Air billet cage – High-end upgrade for zero-compromise builds
Reliability & Rev Limiter
Rev limiter set at 14,100 RPM to:
• Extend engine life
• Reduce maintenance
• Avoid unnecessary mid-air ignition cuts
👉 A properly mapped bike lets you upshift earlier — for better control and faster acceleration.
Recommended Gearing
• 14-52 – D-Spec gearing for better traction and stability (118-link chain)
• 13-50 – More aggressive off-the-line feel
• XC-F & woods riders – Often run 13-50 stock gearing
Map Switch & Wi-Fi Module – Advanced Tuning Options
Option 1 – Two maps on the ECU
Example: one for pump fuel + one for race fuel
Switch between them with the handlebar button
Programmable via the WiGET app
✅ Perfect if you practice and race on the same bike.
Option 2 – On-the-fly tuning tool
Same base map loaded twice
One is modified for testing purposes
Switch between maps while riding
Once you’re happy with the result, we lock in the final version — and you can remove the module.
💡 This method is often used by riders who want a fully personalized setup — but a clean, minimalist race-day configuration.
