Tekno NB/EB48 2.2 : R piston in Front, 575 warm - 525 cold temperature : F piston in Rear, 450 warm - 400 cold temperature (recommended oil for inside hole on arms)

Tekno NT/ET48 2.2 : F piston in Front, 700 warm - 650 cold temperature : R piston in Rear, 575 warm - 525 cold temperature (recommended oil for middle hole on arms)

The pistons are precision drilled on the CnC. Hand drilling this hole pattern does not have the same results. The small holes HAVE to be clean with NO burr, and they have to be straight. Thats impossible to do by hand.

The VRP ‘XV4’ Pistons are designed to have a washer under and over them. It is important to run washers and that they are correctly installed. Each set of pistons is supplied with a Washer Hardware Pack to make sure you have what you need to install them.

Each set of pistons comes with 4 different upper washers that are color coded. The washers are made to cover the rubber valves to give different rebound rates.

Black / Red / Gold / Blue : Most rebound Black, to least rebound Blue

For tracks that are loose and low grip, or very blown out with large ruts, more rebound is preferred. On smooth or tracks that have very high grip, less rebound is preferred. We suggest starting with the Red Washer in both the front and rear pistons.
