Derbi Euro 3-4 Balance Shaft TXT Exhaust

Balance shaft by manufacturer TXT Exhaust for Derbi Euro 3-4.

The reinforced TXT balance shaft is the key component to replace the original part in Derbi Euro 3 and 4 engines, especially when you are looking for greater reliability and smoother engine operation. As it is machined from high-strength steel, this shaft withstands wear and the demands of intensive use much better, eliminating the risk of premature breakage that standard components often suffer.

Its installation allows you to reduce engine vibrations, ensuring the engine block runs more smoothly and efficiently. In addition, thanks to its precise tightening tolerance, welding is not required during assembly, making the replacement or upgrade process of your mechanical setup easier.

This shaft is available in two versions depending on your setup:

• 50/80cc version: Maintains the characteristics and weight of the original, serving as a direct replacement for stock engines or light modifications.
• 90/115cc version: Features an increased counterweight, necessary to compensate for the greater weight of pistons in high-displacement setups and to avoid excessive vibrations.

Technical specifications

• Material: High-strength steel.
• Compatibility: Derbi Euro 3 and Euro 4 engines.
• Versions: 50/80cc (standard) and 90/115cc (increased counterweight).
• Assembly: No welding required.

Attention! Installing the 90/115cc version shaft on NEO-type crankcases requires prior machining for correct installation.
