When it comes to a TMAX big bore kit, many think only about “more power.” The reality is more nuanced: increasing displacement affects the ride, engine response, torque curve, and electronic management.

With over 20 years of experience, Magistrati Racing® develops kits and builds that not only increase TMAX horsepower, but ensure sustainable, reliable, and dyno-proven performance.

TMAX increased displacement: what it means for the engine

A 595 cc big bore kit for TMAX 560 from Magistrati Racing® is more than just a larger piston. Increasing displacement affects:

• Torque and power: more volume allows more air and fuel, increasing real power across all RPMs
• Smoothness of delivery: proper ECU tuning avoids torque dips or spikes
• Mechanical harmony: pistons, camshafts, and adjustable gears must work in sync

The result is a TMAX that pushes strongly yet remains drivable and reliable, even after long-term use.

Where mechanics and electronics meet

Increasing displacement without tuning electronics is like having a Ferrari without an ECU: wasted power, irregular torque curve, and increased wear.

Magistrati Racing® uses the Dynojet dyno to measure the real effect of each kit, combining mechanics and electronics. This allows us to:

• check real wheel power (read about our Dynojet here)
• optimize ECU mapping for each configuration (ECU TMAX tuning explained)
• harmonize the torque curve with camshafts and adjustable gears (Choosing the right TMAX camshaft)

This approach delivers usable TMAX horsepower while avoiding mechanical stress.

595 cc big bore kit: more displacement, more control

Simply increasing cylinder volume is not enough: the engine and electronics must be guided to achieve maximum effective performance.

With the 595 cc Magistrati Racing® kit:

• power is smooth across the rev range
• torque is progressive and manageable
• electronics work in perfect synergy with mechanics
• the TMAX remains reliable over time

The result is a ride that is fluid, engaging, and safe.

• TMAX Modifications: why “one-size-fits-all” doesn’t work
• TMAX Camshafts: why there is no “best” one, only the right one
• ECU TMAX: why electronics is the true heart of performance

Conclusion: increasing displacement with method

Upgrading displacement is not a trend. It is a technical choice, balanced with electronics and other components.

The 595 cc Magistrati Racing® TMAX kit ensures sustainable, measured, and reliable performance without compromise.
