Gas Dirt Bikes for Sale in Canada | 70cc–125cc

  Venom Thunder 125cc Dirt Bike with 4-Speed Manual Transmission Manual-clutch control. Kick-start power. 17/14-inch wheels. The Venom Thunder 125cc Dirt Bike combines a four-stroke gas engine with a 4-speed manual transmission and hand-operated clutch. For riders ready for traditional motorcycle controls, the Thunder puts gear selection, clutch engagement and throttle control in the rider's hands. A 33-inch seat height, 17-inch front wheel and 14-inch rear wheel give the Thunder its off-road stance. Front and rear hydraulic disc brakes, a Volt V-Force adjustable rear shock, a front headlight and an engine hour meter bring useful equipment to this manual dirt bike for Canadian riders. What Makes the Thunder 125cc Stand Out? YX125 four-stroke engine: The air-cooled, single-cylinder engine has a listed displacement of 124cc within the 125cc class. A PZ26 carburetor supplies fuel. The bike is kick-start only and does not use a battery. Four-speed manual transmission: A hand-operated clutch and four forward gears provide a traditional motorcycle riding experience. The rider controls clutch engagement and gear changes rather than relying on an automatic transmission. 17-inch front and 14-inch rear wheels: The Thunder uses a 70/100-17 front tire and 90/100-14 rear tire, both with off-road tread and inner tubes. Hydraulic disc brakes at both wheels: Front and rear hydraulic disc brakes provide dedicated braking systems for each end of the bike. Adjustable rear suspension: A Volt V-Force rear shock provides suspension adjustment, alongside front suspension forks and a steel rear swing arm. Follow the model-specific instructions when setting up the suspension. Headlight and engine hour meter: The included front headlight adds illumination, while the hour meter tracks engine running time to help monitor scheduled maintenance. Two keys are included. Distinctive frame and drivetrain equipment: An orange powder-coated reinforced frame, forged aluminum triple clamps, a 428 gold drive chain and a racing-style muffler and exhaust complete the Thunder's motocross-inspired appearance. Rider Fit and Dimensions The Thunder measures 75 inches long × 31 inches wide × 42 inches high. Its seat height is 33 inches (approximately 83.8 cm), with a 48-inch wheelbase (approximately 121.9 cm). The minimum rider age is 16 years, with a maximum rider weight of 250 lb (approximately 113.4 kg). The listed minimum rider height is 5 ft 4 in (approximately 162.6 cm).

Frequently Asked Questions Is the Thunder 125cc automatic or manual? The Thunder has a 4-speed manual transmission with a hand-operated clutch. The rider controls clutch engagement and selects the gears. It is not an automatic or semi-automatic dirt bike, so clutch and shifting skills are part of learning to ride it.

Follow the supplied starting instructions. How fast does the Thunder 125cc go? The listed maximum speed is 55 mph, approximately 89 km/h. Actual speed depends on rider load, terrain, setup and riding conditions. Ride at a speed appropriate for the rider's ability and surroundings. What age and size rider is the Thunder suitable for? The minimum rider age is 16 years, with a maximum rider weight of 250 lb (approximately 113.4 kg). The listed minimum rider height is 5 ft 4 in (approximately 162.6 cm), and the seat height is 33 inches (approximately 83.8 cm). The rider must comfortably reach and operate the clutch, throttle, brakes and shifter and support the bike when stopped. Age, height and weight alone do not establish suitability. Follow the manufacturer's manual, vehicle labels and applicable local riding requirements. What wheels and brakes does it have? The Thunder has a 17-inch front wheel and 14-inch rear wheel, fitted with 70/100-17 front and 90/100-14 rear off-road tube-type tires. Hydraulic disc brakes are fitted at both wheels. What does the hour meter do? The installed hour meter records engine running time. Use it alongside the maintenance schedule to track when inspections and servicing are due, rather than relying only on how many days have passed since the last ride. Is the rear suspension adjustable? Yes. The Thunder includes a Volt V-Force adjustable rear shock. Follow the model-specific setup instructions and have suspension adjustments checked as part of the bike's inspection. Front suspension forks are also included. Does the headlight make it a street-legal motorcycle? The Thunder is sold as an off-road dirt bike. The included headlight does not establish road-registration eligibility. Confirm the requirements for your intended riding location before purchasing. Does it arrive fully assembled? The standard crated Thunder is listed as approximately 80% assembled. Remaining work includes installing the front and rear shocks, front tire and fender, and handlebars, followed by pre-delivery inspection (PDI) and testing. No battery installation or connection is required. Confirm the assembly service selected for your order and follow the model-specific instructions. Venom's Canadian terms require this work to be performed by a certified mechanic. Keep the mechanic's documentation. A paid pre-shipment assembly service can be arranged with Venom, and the bike should still be inspected after transportation. Review our assembly and PDI guide alongside the Thunder's own instructions. What maintenance does the Thunder need? Follow the model-specific schedule for engine oil, the air filter, spark plug, carburetor, clutch, drive chain and sprockets. Inspect the brakes, tires, spokes, steering, suspension and fasteners regularly. The hour meter helps you track engine hours between service checks. What warranty is included in Canada? The Thunder includes a 1-year standard parts warranty for eligible defective mechanical and electrical components, subject to the terms. Coverage begins when you receive the bike. During the first month, approved replacement parts and their shipping are covered. For the remainder of the first year, covered parts are supplied and the customer pays shipping. Labour, normal wear, physical damage and the policy's other exclusions apply. Read the complete Canadian warranty and purchase terms. How does shipping work within Canada?
