Dal Soggio SPHERE 3.0 KYB Spring Fork Cartridge Kit

The Dal Soggio SPHERE 3.0 KYB Spring Cartridge Kit is a high-performance suspension upgrade developed specifically for compatible KYB coil-spring front forks used on Beta RR, Sherco, and Yamaha Enduro motorcycles.

Dal Soggio officially identifies SKU 1P.SPH.KYBAMOLLA3.0 as Sphere KYB a molla 3.0, with an Enduro application range covering compatible motorcycles equipped with the appropriate KYB fork platform from 2017 through 2025.

SPHERE 3.0 replaces the original internal damping system with Dal Soggio Race’s sealed and pressurized hydraulic cartridge, developed through extensive dyno and track testing to improve fork sensitivity, precision, hydraulic control, and rider feedback.

A major development of SPHERE 3.0 is its redesigned bladder, featuring a thinner yet stronger construction. This improves cartridge sensitivity and allows greater precision during hydraulic bleeding.

The redesigned compression base valve provides separate High-Speed Compression and Low-Speed Compression settings. These two damping ranges can therefore be adjusted independently, allowing the suspension technician to tune the fork more precisely according to terrain, rider weight, speed, and riding style.

SPHERE 3.0 also features a larger 36 mm compression piston, replacing the 28 mm piston used in the previous generation. The increased piston diameter is designed to improve the linearity of the fork’s hydraulic response throughout the suspension stroke.

Another major innovation is Dal Soggio’s Direct Flow Technology. The compression piston receives oil directly rather than through the previous Z-shaped internal passages, reducing unnecessary hydraulic restriction and stress within the cartridge.

For Enduro use, this combination is designed to provide increased front-wheel sensitivity over roots, rocks, ruts, braking bumps, and loose terrain while maintaining sufficient support during faster and harder impacts.

Dal Soggio specifies CUBE Fork Oil 5W for use inside the SPHERE hydraulic cartridge system.

Application & Compatibility

The 1P.SPH.KYBAMOLLA3.0 SPHERE 3.0 is designed for compatible KYB coil-spring front forks used on Enduro motorcycles.

Dal Soggio officially classifies this version as:

KYB – Beta RR / Sherco / Yamaha with KYB fork – Enduro – 2017-2025.

Compatibility is determined primarily by the actual KYB fork platform, not simply by motorcycle brand, displacement, or model year.

This is especially important for Beta motorcycles because standard RR and Racing/Race versions can use different suspension platforms. This KYB version should therefore not be assumed compatible with Beta RR models equipped with Sachs forks.

Likewise, Sherco and Yamaha applications must be equipped with the compatible KYB coil-spring fork configuration.

Hydraulic System & Performance

SPHERE 3.0 replaces the original damping internals with a sealed and pressurized hydraulic cartridge engineered to provide increased precision and sensitivity.

The new bladder helps improve hydraulic responsiveness and cartridge bleeding precision.

The 36 mm compression piston provides a larger working diameter than the previous 28 mm SPHERE configuration and contributes to a more linear hydraulic response throughout the stroke.

Separate high-speed and low-speed compression circuits provide increased tuning flexibility for different terrain and rider requirements.

With Direct Flow Technology, oil reaches the compression piston directly, avoiding the previous indirect Z-shaped routing and reducing unnecessary internal hydraulic restriction.

Enduro Application

This SPHERE 3.0 version is configured specifically for Enduro motorcycles using a compatible KYB spring fork.

Enduro suspension must combine sensitivity with sufficient hydraulic support across a broad range of terrain and suspension speeds.

The cartridge is designed to improve front-wheel feedback and control over:

• roots and rocks;
• ruts and technical sections;
• braking bumps;
• loose and low-grip terrain;
• square-edge impacts;
• higher-speed Enduro terrain;
• harder suspension loads and compressions.

The independent compression circuits allow slower chassis movements to be adjusted separately from faster suspension impacts.

Oil & Service

Dal Soggio specifies CUBE Fork Oil 5W for use inside the SPHERE hydraulic cartridge system.

Correct oil quantity, hydraulic bleeding, spring selection, damping adjustment, and chassis balance are essential for proper suspension performance.

Professional installation and setup by a qualified off-road suspension specialist are strongly recommended.

Installation Note

Before installation, confirm:

• correct KYB coil-spring fork platform;
• compatible Beta, Sherco, or Yamaha application;
• Enduro configuration;
• production year within the appropriate platform range;
• correct Dal Soggio SKU 1P.SPH.KYBAMOLLA3.0.

Do not determine compatibility from motorcycle model alone. The actual fork fitted to the motorcycle must be identified before ordering or installation.

Final spring setup, oil level, damping adjustment, and chassis balance should be configured according to rider weight, skill level, riding style, and terrain.
