🔥 D-Tracker 250 Motard 352cc by Keng Engine 🔥

Not just a normal engine swap…
This bike was built with a fully custom setup from the ground up 😈🚀

✔ 352cc Engine Setup
✔ Custom-built wiring harness
✔ CRF250 ECU conversion
✔ DynoJet custom tuning
✔ Full performance setup by Keng Engine Chiang Mai

This project combines Kawasaki chassis + Honda ECU technology + custom tuning experience into one crazy machine 🔥

📈 Dyno Result:
✔ Max Power: 37.03 HP @ 8,750 RPM
✔ Max Torque: 24.33 lb-ft @ 6,810 RPM

The most impressive part is not only the peak number —
the power delivery is smooth, aggressive, and very usable throughout the RPM range.

📊 Dyno Graph Explanation:
✔ Strong low-end torque
✔ Hard-hitting mid-range power
✔ Smooth top-end pull up to nearly 9,000 RPM
✔ Stable AFR for better combustion and engine safety

This means:
⚡ Faster acceleration
⚡ Immediate throttle response
⚡ Strong corner exit power
⚡ Perfect for street riding and supermoto fun

A custom-built machine like this takes time, testing, fabrication, wiring, dyno tuning, and real-world experience.
This is not a bolt-on setup — this is a full custom performance build 🔥

🇲🇾 Hello my Malaysian friends 🙏

I’m planning to travel to Malaysia soon, around Kuala Lumpur or nearby areas.

If any of my friends or customers in Malaysia need anything from Keng Engine, please feel free to message me.

Maybe I can bring some parts with me during this trip — small parts, special parts, or anything you need from Thailand.

If you have any bike project, engine upgrade, CRF / CBR / KLX parts, camshaft, big bore kit, clutch upgrade, intake, ECU, or tuning questions, you can talk to me first.

This trip is not only business — I’m happy to meet friends, talk about bikes, and help if I can.

If you need anything, please let me know before I travel so I can prepare it for you.

See you soon, Malaysia 🇲🇾
