Modular VOCA Race Head 46mm, Yamaha DT LC/D - black

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

The Voca Race Head Ø46mm 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 Ø46mm 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.

With the possibility of changing the combustion chambers (insert), this cylinder head allows for a different setup for every preference. This insert is recommended for the most experienced tuners, who have a lathe to shape the insert preparation.

Cylinder head:

This kit includes an insert optimized for Ø46mm pistons. Suitable for original stroke and original cylinders rebored to this diameter. It features a locking pin, which prevents the insert from rotating when tightening or loosening the spark plug. The optimal squish for this insert is 0.45mm-0.6mm.

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:

• Black cylinder head cover
• Ø46mm insert
• O-ring gasket kit
• Water connector
• Anti-rotation locking pin
• Assembly instructions

High quality product, 100% Voca Racing!
