This is also the flywheel side bearing for VNA, VNB, VBB, VBA, VLB, VLA, VBC, VNC, VB1, VS5 and VL1 VL3, so, for those, models you'll need 2. On P series scooters, use 133068 for the flywheel side bearing. And, if you've already torn your engine apart, why not replace the rear hub bearing while you're in there? (Part # 90025).
