💪 Why Riders Choose the Storm
⚡ 125cc 4-Stroke Power
The Storm uses a 125cc, single-cylinder, 4-stroke, air-cooled engine with a listed maximum output of 6.3 kW at 7,500 rpm — equivalent to 6,300 watts.
That gives the bike the power needed for recreational trail riding while keeping the engine configuration relatively simple and easy to operate.
🔄 Automatic Transmission
No manual clutch work is required.
The automatic transmission makes the DB-K025 particularly approachable for riders who want to concentrate on steering, throttle control, braking, and the terrain instead of manually shifting gears.
🔑 Electric Start
Press the starter and get the engine running without relying on a kick-start procedure.
It's especially convenient when stopping and restarting during a day of trail riding.
🛞 14"/12" Off-Road Wheel Setup
The Storm uses:
-
60/100-14" front tire
-
80/100-12" rear tire
The larger front wheel helps maintain stability over uneven terrain, while the 12" rear wheel complements the compact dirt-bike chassis.
🌀 Upgraded Inverted Front Fork
The front suspension uses an inverted telescopic fork measuring 33 × 650 mm.
The inverted design helps provide a rigid front-end platform for off-road riding while helping the bike remain composed over uneven ground.
🔩 Rear Single-Shock Suspension
A single 10 × 270 mm rear shock supports the rear of the bike and works with the steel frame and front fork to create a balanced suspension system.
🛑 Hydraulic Disc Brakes
The Storm is equipped with hydraulic disc brakes at both ends:
Front: 220 mm disc with hydraulic double-piston caliper
Rear: 190 mm disc with hydraulic single-piston caliper
Hydraulic braking provides strong, consistent control for recreational off-road riding.
🏗️ Cradle-Type Steel Tube Frame
The cradle-type steel tube frame is designed for strength and rigidity while keeping the overall motorcycle compact.
It's an important part of the Storm's off-road chassis, particularly when riding across uneven trails and changing terrain.
⛽ 3.5L Fuel Tank
The 3.5-liter / 0.92-gallon fuel tank provides the fuel capacity for recreational riding without adding unnecessary bulk to the compact chassis.

🚀 Performance
6,300 Watts of Maximum Engine Power
