the art of balance: low and centered
In 2001 we introduced Right Side Drive (RSD) for ground-up, wide tire customs. Any primary drive setup could be used in conjunction with RSD, but there was a problem. Actually not a problem but more like an opportunity. Using a left side drive primary in conjunction with RSD left a gaping hole between the inside of the primary and the left side of the transmission case - the space once occupied by the left side drive pulley. Our new DSSC primary slams the clutch inward 2.3-inch into the space once occupied by the pulley - thus the phrase SLAM CLUTCH.
While we were slamming the clutch inward, we rotated the starter down into the vacant space behind the transmission case - thus the phrase DROP STARTER. Lowering the starter in the chassis permitted seat heights to be lowered up to 2.5-inch. It also cleaned up the left side view profile.
DSSC is a complete drivetrain unit consisting of a Right Side Drive transmission and an enclosed primary drive. The inner primary, outer primary, tranny case, trap door, top cover, and pulley shroud are all carved out of 6061-T6 billet. We cut no corners to make this premium drivetrain look like Tiffany jewelry and take punishment from a big inch motor.
DSSC is a complete RSD drivetrain system and is compatible, without modification, with Daytec, Rolling Thunder, Dakota Thunder, and similar RSD Softail and Hardtail frames with zero engine offset and a left tranny offset. The offset is built into the inner primary - no spacer required. DSSC is set up for 240/250 tire applications using a 1-inch belt. 280 and 300 tire applications are possible with a 530 O-ring and an offset sprocket, call for details.
