Colaça VOCA Race Head DT 100cc (Ø54mm) Red

Voca Race Head Raw Red for Yamaha DT LC/D 54MM

The Voca Race Head Ø54mm has completely revolutionised the world of square cylinder preparations for DT and TZR, opening up an infinite variety of possibilities.

This two-piece modular cylinder head consists of an anodised aluminium cover and a removable Ø54mm insert, all accompanied by their respective O-rings. Manufactured from a single piece of aluminium, then CNC machined to achieve this 100% Racing-look part.

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

With the possibility of changing combustion chambers (cylinder head), this cylinder head allows for a different setup for every taste. For other preparations, VOCA offers a completely blank cylinder head, where you can prepare your own design for different pistons or crankshaft strokes.

Cooling:
Cooling has been improved compared to the original, optimising internal flow and increasing performance. The great novelty of this cylinder head is the possibility of rotating it 180º, allowing the mounting of various radiators.
Right side, using one radiator
Left side, using two radiators
For high-performance preparations, the use of two radiators is recommended.

Temperature Sensor:
The thread allows the use of the original temperature sensor. Replacement sensors are also available for use with digital control panels, for example, the Voca Racing control panel. For digital temperature sensors, you must use Koso, Stage6 sensors (M10x1mm) and be careful when selecting the plug colour (black or white).

Seals:
Another important feature is the replacement of the original single gasket with O-rings. These ensure better sealing and reliability.
Seal kits are available as spare parts.

The kit includes:
Red cylinder head cover
Ø54mm insert
O-ring kit
Water connector
Anti-rotation locking pin
