VOCA Modular Cylinder Head Race Head 54mm, Yamaha DT LC/D - blue

Voca Race Raw blue cylinder head for Yamaha DT LC/D

The Voca Race Head Ø54mm has completely revolutionized the world of DT and TZR square cylinder tuning, making an infinite variety of possibilities possible.

This two-piece modular cylinder head is composed of an anodized aluminum cover and a removable Ø54mm insert, all accompanied by their respective O-rings. Made from a single piece of aluminum, later CNC machined to achieve this part with a 100% Racing look.

Cylinder head:

This kit includes an insert for 54mm pistons. Suitable for 42/43mm stroke and VOCA, Italkit, Alukit cylinders. It is important to maintain the recommended squish of 0.08mm for other strokes and longer connecting rods. It features a locking pin, which prevents the insert from rotating when tightening or loosening the spark plug.

With the possibility of changing the combustion chambers (insert), this cylinder head allows for different setups to suit every preference. For other setups, VOCA offers a completely blank insert, where you can create your own design for different pistons or crankshaft strokes.

Cooling:

The cooling has been improved compared to the original, optimizing the internal flow and increasing performance. The great innovation of this cylinder head is the possibility of rotating it 180º, allowing the installation of multiple radiators.

• Right side, use of one radiator
• Left side, use of two radiators

For high-performance setups, the use of two radiators is recommended.

Temperature sensor:

The thread allows the use of the original temperature probe. We also offer aftermarket sensors for use with digital gauges, such as the Voca Racing gauge. For digital temperature sensors, you should use Koso, Stage6 (M10x1mm) sensors and pay attention when selecting the plug color (black or white).

Gaskets:

Another of the most important features is the replacement of the original simple gasket with O-rings. They ensure greater sealing and reliability.
Gasket kits are available as replacements.

The kit includes:

• Blue cylinder head cover
• Ø54mm insert
• O-ring gasket kit
• Water connector
• Anti-rotation locking pin
• Assembly instructions

High quality product, Voca 100% Racing!
