Aprilia RSV4/Tuono V4 1100 Chain Adjuster Blocks – DBK

Aprilia RSV4/Tuono V4 1100 Chain Adjuster Blocks

The Aprilia RSV4/Tuono V4 1100 Chain Adjuster Blocks are high-performance upgrades designed to replace the loose, roughly stamped factory chain adjustments on your Aprilia swingarm. Made in Italy by DBK Special Parts to achieve absolute wheel alignment precision and sharpen your superbike’s styling.

When you mash the throttle on a high-torque V4 powerplant, the immense tension pull can push subpar axle blocks out of true if not secured perfectly. DBK Special Parts eliminates this vulnerability by engineering tight, zero-tolerance slider blocks that slide smoothly within the swingarm channel. This provides a rock-solid backing for your rear axle, preventing rear wheel twist and keeping your drivetrain working efficiently.

CNC Machined from 7075 Ergal Billet Aluminum

Following the strict production standards of DBK Special Parts (forged from the track development of Ducabike and Performance Technology), the CTC05 adjuster blocks are CNC-machined from a solid block of high-strength 7075 Ergal billet aluminum. This material swap slashes unsprung rotating mass while offering a significant upgrade in shear strength over soft factory cast aluminum blocks.

To make routine garage maintenance a breeze, each block features high-visibility, laser-etched metric alignment marks. This allows you to measure your wheel alignment down to the millimeter without relying on guesswork. The blocks are finished with a vibrant colored anodization surface treatment that protects the aluminum against harsh chain lubes, chemical cleaners, and road debris.

Advanced Integrated Maintenance Features

As a brilliant design masterstroke, these blocks feature an integrated metric adjustment screw setup that stays firmly seated against the swingarm interior. This design prevents the axle blocks from sliding loosely or slipping backward when you loosen the main axle nut, making quick rear-wheel swaps or trackside gearing changes incredibly fast and precise.

Comprehensive Aprilia V4 Fitment

The CTC05 kit is precisely machined to match the exact interior dimensions and axle diameters of Aprilia’s flagship sport and naked platforms:
