Bonamici Racing Race Top Yoke for Aprilia RSV4 / RR / RF / 1100 Factory (2015-2020) PSA1R

Machined from high-tensile aluminium and built to the exacting standards of Italian race engineering, the Bonamici Racing PSA1R top yoke transforms the steering feel of the Aprilia RSV4 family with a directness and solidity that standard components simply cannot match. Designed specifically for track deployment, this race-specification top yoke delivers measurably sharper steering precision and improved chassis stability lap after lap.

Key Features

• High-tensile aluminium construction offers an exceptional strength-to-weight ratio and long-term durability under race conditions
• Race-specific geometry engineered to improve steering precision and front-end feel on the Aprilia RSV4 platform
• Available in anodised black or anodised silver, each finish applied to a quality that complements the RSV4's aggressive bodywork
• Bolt-on fitment with no frame or fork modifications required, keeping installation clean and reversible
• 100% Made in Italy — every component manufactured and quality-checked at Bonamici Racing's Italian facility
• Note: the steering plate for the ignition barrel (key block) is not included, as is standard with race-specification yokes of this type

Premium Construction and Race Pedigree

The PSA1R is not an aftermarket cosmetic upgrade — it is a functional race component developed by Bonamici Racing, a brand whose parts appear in World Superbike paddocks and on privately entered track machines across Europe. The top yoke is CNC-machined from high-tensile aluminium billet, which eliminates the porosity and inconsistency inherent in cast parts. The result is a component that is rigid where rigidity counts, precisely dimensioned at every interface, and finished to a standard that ages well even in punishing track environments.

The anodised finish — available in either black or silver — is not merely decorative. Anodising creates a hard, integrated surface layer that resists corrosion, abrasion, and the heat cycles experienced under race use, keeping the yoke looking and performing as intended throughout its working life.

Steering Precision and Chassis Stability

On a machine as capable as the Aprilia RSV4, the connection between rider input and front-end response is critical. The PSA1R top yoke tightens that connection by providing a more consistent clamping interface at the fork tops and a stiffer, more accurately located steering axis. Riders switching from the original yoke typically report a more confident turn-in character and reduced vagueness under hard braking — qualities that matter whether you are chasing lap times on a circuit or demanding precision on a fast road.

Fitment and Compatibility

The Bonamici Racing PSA1R top yoke is designed and manufactured to fit the following Aprilia models:

• Aprilia RSV4 (2015-2020)
• Aprilia RSV4 Factory (2015-2020)
• Aprilia RSV4 1100 Factory (2015-2020)
• Aprilia RSV4 R (2015-2020)
• Aprilia RSV4 RR (2015-2020)
• Aprilia RSV4 RF (2015-2020)

No modifications to the forks, frame, or steering head are required. Please note that this is the race version and does not include the steering plate for the ignition barrel (key block).
