Why Riders Choose the Non-LE Sigma

The 2025 non-Limited Edition Sigma gives riders the full 98V experience at a more accessible price. The torque delivery, the rigid chassis, and the long wheelbase translate to strong straight-line stability and a planted feel in high-speed sections. The Samsung pack provides excellent voltage support under load, and the regen tuning makes steep descents more controlled while improving range.

Altis designed this platform to be simple to maintain and easy to upgrade. Out of the box, the suspension, geometry, and power system give riders enough performance to handle single-track, MX practice, and everyday trail riding without immediate modifications.

Who the 2025 Sigma (Standard Edition) Is Built For

• Riders stepping up from 60V and 72V platforms
• Off-road and single-track riders who want high torque and smooth power
• MX riders who want a lightweight EMoto with real voltage overhead
• Anyone who wants a ready-to-ride 98V system without paying Limited Edition pricing
• Riders comparing Sur-Ron, Talaria, and similar mid-weight e-motos

Fitment

• Applies to the 2025 Altis Sigma Standard Edition
• Covers both 19/19 and 19/16 factory wheel configurations
• Compatible with all OEM Altis Sigma 98V components, chargers, and accessories
