Crankshaft Pin DRT Eccentric
pin long stroke for Vespa
125 GTR 2°/TS 2°/150 Sprint V
2°/Super 2°/200 Rally 2°
Ø 20 mm,
from 60 to 58 or 62mm stroke
With DRT’s excentric crankshaft pin, the stroke of a crankshaft can be reduced or increased by 2mm. The pin must be pressed in instead of the original. Further work is not required. So, depending on the pin, it is possible to reach the fabulous and high torque 62 mm stroke.
SIP-TIP: Even though the crankshaft pin is set eccentrically, the use of the usual size bearing (20 x 26 x 15mm, Art. Nr.: GDT0304A) is still possible. During assembly lubricate the crankpin with plenty of oil first. Starting with the bearing held at a slight angle, screw it firmly but gently into position.
