Cylinder Voca BigBore 100cc d.54mm / 43mm stroke Yamaha DT

Cylinder kit Voca BigBore 100cc Yamaha DT80

Cylinder Voca Racing BigBore 100cc d.54mm / 43mm stroke for Yamaha DT 50 / DT 80 / RD 80 and TZR 80 up to 2001. High-performance aluminum racing cylinder.

After months of development on the track and dyno, Voca Racing presents this powerful 100cc cylinder for water-cooled Yamaha DT engines. It features a high-quality aluminum construction with chrome/nickel coating, 5 transfer ports, and a split exhaust port. Delivered with a 53.95mm Vertex piston and single piston ring.

The 54mm bore combined with a 43mm stroke gives a full 100cc displacement — serious power for your moped. Only compatible with 43mm / 85mm crankshafts.

The matching modular Race Head cylinder heads are available in 3 colors: Blue, black and red.

To utilize the full power of the 100cc cylinder efficiently and reliably, we recommend using a racing crankshaft such as the HQ Racing crankshaft with 43mm stroke / 85mm connecting rod. Of course, you should also use a suitable tuning exhaust such as the Voca BigBore 100cc, available as an exhaust with carbon ESD and exhaust with Kevlar ESD.
