Specialized Turbo Kenevo SL 2 Expert 2025: Technical Analysis, Testing, and Performance Evaluation
The Specialized Turbo Kenevo SL 2 Expert, in its 2025 configuration, is positioned in the light Enduro electric mountain bike (e-MTB) segment, representing the evolution of a concept aimed at minimizing the difference in maneuverability compared to muscular (non-electric) MTBs of equivalent travel. This article provides a detailed and objective analysis of the technical specifications, trail performance, and constructive features of the Expert model.
Ebike Specialized Turbo Kenevo SL 2 Expert 2025: Build Quality
The Kenevo SL 2 Expert is built according to the standards of Light e-MTB design, where weight reduction is a determining factor.
Frame
The frame is made from FACT 11m carbon fiber, a material selected for the optimal balance between lightness, stiffness, and structural resistance. The carbon layup is specifically optimized for Enduro riding, aiming to minimize lateral and torsional flex—a crucial aspect for steering precision on fast, technical terrains. The design is a carbon monocoque type.
Adjustable Geometry: A distinctive element is the ability to customize the geometry through a system of reversible chips and headset cups. This allows for up to six different configurations, varying the head tube angle (typically between 62.5∘ and 64.5∘) and the bottom bracket height (±6 mm), enabling targeted adaptation to the rider's preferences and the type of trail (more open and stable for descending, or more closed for maneuverability).
Travel: The Six Bar suspension system (six bars, six pivots), specific to Specialized, offers 170 mm of travel both front and rear, positioning it among long-travel Enduro e-MTBs.
Assembly (Expert Specification)
The Expert build is positioned at a mid-to-high level, optimized for downhill performance:
Suspension: It typically features high-level components, such as the FOX Float 38 Performance Elite fork and the FOX Float X2 Performance Elite shock absorber. This configuration guarantees ample adjustments (compression and rebound) and high performance even on complex trails.
Drivetrain: It often includes the wireless SRAM GX Eagle Transmission (T-Type) AXS 12-speed drivetrain, which provides precise gear shifting even under load.
Brakes: The brakes are generally powerful, such as the SRAM Code Silver Stealth with 220 mm (front) and 200 mm (rear) rotors, essential for heat management and modulation on long, demanding descents.
Wheels and Tires: Roval Traverse 29" wheels (sometimes with a Mullet setup), paired with tires featuring the Grid Trail casing and Gripton T9 compound (softer for grip) on the front, balancing resistance and traction.
Ebike Specialized Turbo Kenevo SL 2 Expert 2025: Motor and Performance
The electric motor is the Turbo SL 1.2 unit, a central element in Specialized's SL (Super Light) concept.
The motor is the Specialized SL 1.2 Custom Rx Trail Tuned, which represents a significant upgrade from the previous generation, SL 1.1. In terms of specifications, the motor delivers a maximum power output of 320 Watts, marking an increase of approximately ∼33% compared to the SL 1.1. The maximum torque is 50 Nm, an increase of ∼43%. This power boost is crucial for improving the effectiveness of the assisted pedaling on climbs.
The bike is powered by an integrated battery, the Specialized SL1-320, at 320 Wh (Lipo). This battery, which contributes to the bike's low overall weight, is not easily removable by the user. To increase range, an optional 160 Wh Range Extender is available, bringing the total capacity to 480 Wh.
The measured weight for the S4 size is around 19.5 - 19.7 kg (approximately 42 lb, 15.8 oz), an extremely competitive figure for an Enduro e-MTB with 170 mm of travel.
Performance and Riding Feel:
The SL 1.2 motor offers smooth and natural assistance. Although its peak torque is lower than full power motors (∼85 - 90 Nm), it is significantly boosted to tackle technical and steep climbs. Low noise is a relevant advantage, improving the overall experience. The system is managed by the integrated MasterMind Turbo Control Unit (TCU), which provides real-time data and allows for fine-tuning (MicroTune) of assistance levels in 10% increments.
Ebike Specialized Turbo Kenevo SL 2 Expert 2025: Comfort and Handling
The Kenevo SL 2's design is geared towards typical Enduro aggressiveness, but with a balance that does not sacrifice comfort over long distances.
Comfort
Ergonomics and Riding Position: The bike features a generous reach and a steep seat tube angle (approximately 76∘), which places the rider in a central and efficient position for climbing. The stance is commanding and focused on control.
Suspension: The Six Bar system is designed to offer optimal behavior, being sensitive to small bumps (improving comfort and traction) while being progressive in the final part of the stroke to absorb landings and significant impacts.
Handling
The Kenevo SL 2 Expert is intrinsically a downhill machine, optimized for the agility typical of a muscular bike despite its motorization.
Maneuverability and Agility: The low weight (under 20 kg in the Expert configuration) is the key factor that distinguishes it from full power e-MTBs and confers superior agility in changes of direction and during jumps or aerial maneuvers.
Stability: The slack geometry (relaxed head angle) and long wheelbase contribute to high stability at high speeds and on rough terrain, instilling confidence.
Climbing Behavior: The SL 1.2 motor is sufficient to tackle most climbs, but it requires greater muscular input compared to 85 - 90 Nm motors. The boost, while more powerful than the previous generation, remains less "instantaneous" on technical sections and at very low cadences, demanding a fit rider.
Ebike Specialized Turbo Kenevo SL 2 Expert 2025: Real-World Range
Range is the parameter that undergoes the greatest variation in the Light e-MTB segment.
Theoretical Range: Specialized claims up to ∼5 hours of range with the 320 Wh battery alone under ideal conditions and in Eco mode.
Real-World Range (Reference): In mixed Enduro use (alternating Trail/Turbo modes), the actual range generally stands at around 1,000 - 1,300 meters of elevation gain (positive) for the 320 Wh battery alone.
Extension: The use of the optional 160 Wh Range Extender increases the overall range to approximately 1,500 - 2,000 meters of elevation gain, making it competitive with many full power e-MTBs in standard configuration.
