ORF 110cc Kids Kick Start Dirt Bike | Fast UK Delivery

At the absolute core of the ORF 110cc sits a heavy-duty, commercial-grade Fenghong 110cc horizontal single-cylinder engine. Unlike older-generation, high-strung youth bikes that rely on erratic two-stroke power delivery, the ORF platform utilizes advanced four-stroke engineering. This mechanical design delivers an incredibly smooth, predictable, and linear power curve throughout the entire RPM range.

The engine displaces a true 107ml, featuring a highly balanced bore-to-stroke profile optimized specifically for low-to-mid range torque production. Generating a maximum power output of 5.0 kW at 8,000 RPM paired with a peak torque rating of 7.5 N.m at 5,500 RPM, this engine gives junior riders more than enough muscle to punch up steep inclines, clear muddy ruts, and power out of loose dirt corners without ever feeling overwhelming or snatchy.

The horizontal layout keeps the overall center of gravity incredibly low to the ground, significantly enhancing the bike's natural balance and agile cornering characteristics. Air-cooling ensures maximum mechanical simplicity: there are no coolant lines to puncture, no radiators to bend in a crash, and no water pumps to maintain. The engine runs on standard unleaded fuel with a 9.0:1 compression ratio, utilizing a precision-tuned PZ19 carburetor that delivers crisp throttle response, optimized fuel efficiency, and hassle-free mechanical starting across varying ambient temperatures and track elevations.

One of the most intimidating hurdles for young riders progressing in the sport is learning how to coordinate a manual hand clutch lever with a foot shifter while simultaneously maintaining throttle control and balance on loose terrain. The ORF 110cc completely eliminates this stress by incorporating a highly advanced, ultra-durable semi-automatic auto-clutch transmission system.

The gearbox features a traditional sequential foot-shift layout tracking through Neutral, 1st, 2nd, 3rd, and 4th gears (N-1-2-3-4). However, because it utilizes a built-in centrifugal automatic clutch assembly, there is no hand clutch lever on the handlebars.

To shift gears, the rider simply rolls off the throttle momentarily and clicks the foot lever up or down. The internal clutch handles the engagement and disengagement automatically, preventing stalling during quick stops or clumsy shifts. This clever configuration allows junior riders to focus 100% of their mental energy on mastering line selection, body positioning, braking points, and balance. It teaches them the crucial muscle memory of foot-shifting through a multi-speed gearbox, preparing them perfectly for a fully manual clutch bike in the future.

Power is transferred from the countershaft sprocket to the rear wheel via a premium, heavy-duty #420 pitch drive chain, driving a perfectly geared 14-tooth front and 41-tooth rear sprocket combination. This gear ratio provides an ideal balance between explosive low-end acceleration for loose terrain and a respectable top-speed cap for wide-open trail fields.

When you are out in the woods or at a remote track, the last thing you want to worry about is an electrical failure, a dead battery, or a faulty starter motor cutting your riding day short. The ORF 110cc embraces pure mechanical reliability by utilizing a traditional, heavy-duty manual kick-start system.

Engineered with a high-leverage kick lever located on the right side of the engine casing, the mechanical primary-kick assembly is designed specifically for smaller legs to operate with ease. Thanks to the low compression nature of the highly efficient 110cc 4-stroke engine and the precise ignition timing of the CDI unit, the bike fires to life with a single, positive kick.

By eliminating the weight and complexity of a heavy starter motor, an onboard battery, and wiring looms, the bike remains lightweight, incredibly nimble, and immune to electrical drain. Whether the bike has been sitting in a cold garage all winter or got completely submerged in a deep puddle on the track, the mechanical kick-start ensures instant, unwavering reliability every single time.

Off-road control, traction, and rider safety are directly dictated by how well the tires stay in contact with the ground. The ORF 110cc sets a new standard in the youth pit bike class by stepping away from basic budget shocks and deploying a race-inspired Up-Side-Down (USD) inverted front fork system.

Measuring 650mm in overall length with a massive 33mm inner fork tube diameter, these inverted forks place the heavier outer sliders at the top of the triple clamps. This structural layout drastically reduces unsprung weight at the front wheel, allowing the front suspension to respond with lighting speed to sudden bumps, sharp rocks, and deep ruts. Offering a generous 110mm of smooth front-wheel travel, these forks soak up hard impacts and jump landings effortlessly while maintaining rigid lateral stability to stop front-end twisting during aggressive cornering.

The rear suspension utilizes a heavy-duty cradle-mounted standard hydraulic monoshock with 43mm of vertical travel. Tuned specifically to accommodate youth rider weights, the rear shock absorber delivers balanced dampening control to prevent the bike from bucking or wallowing over consecutive jumps or rough terrain. Together, this suspension package keeps the bike perfectly level, tracks true through loose berms, and dramatically reduces physical fatigue, allowing your child to ride comfortably for hours.

When it comes to junior motorsport, braking performance is the single most critical safety component. The ORF 110cc leaves absolutely no room for compromise, entirely ditching cheap, high-maintenance mechanical drum brakes in favor of a full front and rear hydraulic disc braking system.

The front wheel is equipped with a massive 210mm ventilated steel disc brake rotor, clamped down by a highly responsive single-piston hydraulic caliper. The rear features a matching 190mm ventilated steel disc brake rotor and single-piston caliper configuration.

Operated via a standard front handlebar lever and a right-foot rear brake pedal, this hydraulic array provides massive, fade-free stopping power with minimal physical effort from the rider. Unlike cable-operated brakes that require constant adjustments and stretch over time, hydraulic lines deliver identical, ultra-sharp modulation and immediate lever feedback in all environments—whether riding through deep mud, standing water, sandy tracks, or dry dust. This gives young riders total control over their speed, allowing them to stop safely and confidently on a dime.

The structural spine of the ORF 110cc is an ultra-rigid, race-proven cradle-style steel tube frame. This frame design completely wraps underneath the engine crankcase, providing an integrated mechanical shield against ground impacts, casing out on obstacles, or flying track debris. The main frame is paired with a heavily reinforced, welded square steel tube swing-arm, engineered specifically to withstand the brutal torsional twisting forces encountered during aggressive trail riding and jump landings.

The bike rolls on a classic pit bike staggered wheel layout, pairing a 14-inch front wheel (wrapped in a chunky, high-grip 70/100-14 knobby tire) with a 12-inch rear wheel (wrapped in a wide 90/100-12 knobby tire). The heavy-duty steel spoke rims are paired with die-cast drum cores to absorb severe impacts without cracking or bending.

Ergonomically, the ORF 110cc is perfectly proportioned for growing youths. It features a highly accessible 730mm seat height that allows mid-sized kids to comfortably plant both feet on the ground when stopped, boosting their confidence during slow-speed maneuvers. Despite the low seat position, the cradle frame design yields an impressive 225mm of ground clearance, allowing the bike to clear large logs, rocks, and track obstacles without bottoming out. With a compact 1,095mm wheelbase, the bike is incredibly nimble, offering razor-sharp turning circles and effortlessly playful handling.

A: The ORF 110cc is primarily engineered for youth riders aged between 7 and 12 years old, depending heavily on their prior riding experience and physical stature. Because children grow at wildly different rates, analyzing their physical height is always a more accurate metric than relying strictly on age.

With a seat height of 730mm, this bike is perfectly tailored for riders who stand between 4 feet 2 inches and 4 feet 10 inches tall. The ultimate sizing rule for safety and confidence is ensuring that while sitting on the gripper seat, your child can firmly plant the balls of both feet—or ideally, sit completely flat-footed—on the ground. This guarantees they can easily maintain balance when coming to a stop, pull away cleanly, and support the bike's 67KG dry weight if they stall or encounter uneven terrain out on the tracks.

A: A semi-automatic transmission combines the mechanical gear selection of an adult motorcycle with the ease-of-use of an automatic scooter. On the left side of the handlebars, there is completely no manual clutch lever to pull. However, down by the left footpeg, there is a traditional sequential motorcycle shift lever that maps through Neutral, 1st, 2nd, 3rd, and 4th gears (N-1-2-3-4).

Inside the engine, a specialized internal centrifugal automatic clutch system handles all the heavy lifting. When the bike is idling in Neutral, the clutch is fully disengaged. When the rider clicks into 1st gear and twists the throttle, the internal clutch automatically engages smoothly as engine RPM rises, seamlessly moving the bike forward.

To shift up into higher gears, the rider simply rolls off the hand throttle for a split second, clicks the foot shifter upward into the next gear, and rolls back onto the power. It is impossible to stall the bike by forgetting to pull a clutch when coming to a stop. This creates an unparalleled learning environment: kids learn how to listen to the engine's RPM pitch and master the physical action of changing gears with their foot, without the constant stress of stalling out or grinding gears due to poor hand-clutch coordination.

A: Not at all! Unlike heavy adult dirt bikes or erratic old 2-stroke engines that can kick back aggressively, the ORF 110cc is a highly refined 4-stroke engine with relatively low compression (9.0:1) and modern CDI ignition.

The kick-start lever is positioned and geared to maximize leverage, meaning it requires very little downward physical effort to spin the engine over. Once the bike is warm, most children over the age of 8 can easily kick-start the bike completely on their own without parental help. Furthermore, because there is no battery, starter motor, or electrical starter relay to fail, the mechanical kick-start guarantees that the bike will fire up even if it has been sitting in a cold shed for months.

A: Out of the box, with a fully opened throttle and an experienced rider shifting efficiently through all 4 gears, the ORF 110cc can reach a maximum top speed of approximately 35 to 40 MPH.

However, because safety is our absolute priority at Patriot Bikes, the ORF 110cc is equipped with an integrated adjustable mechanical throttle limiter located directly on the right handlebar assembly. This parent-controlled safety feature consists of an adjustable stop-screw that physically limits how far the rider can twist the throttle tube.

If your child is completely new to the sport or transitioning to a larger engine size, you can easily wind this screw inward to restrict the throttle opening to just 25% or 50%. This restricts the top speed down to a safe, controlled walking pace (approx. 8 to 12 MPH) for their initial training sessions. As your young rider builds confidence, refines their braking technique, and masters gear selection, you can gradually back the screw out over weeks or months to unlock the engine's full performance potential at a pace you are entirely comfortable with.

A: Yes, the ORF 110cc has been built to withstand the punishing, wet, and muddy off-road environments typical of UK tracks and private trail lands. Unlike many entry-level pit bikes that utilize cheap mechanical cable brakes which instantly lose performance when coated in water or grit, the ORF features a premium front and rear hydraulic disc braking array. Because hydraulic systems are completely sealed from the elements, they deliver identical, ultra-sharp stopping power and exceptional lever feedback whether the bike is running through dry dirt, loose sand, deep puddles, or thick mud.

Furthermore, by ditching an electric start battery and intricate starter electronics, there are no sensitive electrical circuits or exposed battery boxes to short-out when blasting through deep puddles or power-washing the bike after a heavy track day. The high-grip knobby tires feature a deep, aggressive block tread pattern engineered specifically to clear mud quickly from the rotating carcass, ensuring consistent side-bite and straight-line traction through soggy fields and slippery woodland trails.

A: The ORF 110cc features an advanced 4-stroke engine configuration, which means it runs on standard unleaded petrol straight from any regular UK fuel forecourt (Standard E10 or premium E5).

You do not need to buy expensive two-stroke mixing oils, and you do not have to perform messy fuel-to-oil calculations every time you fill up. The engine features an isolated internal oil reservoir within the crankcase that continuously lubricates the internal mechanical components via an onboard oil pump—exactly like a real car or full-sized road motorcycle. You simply pour clean unleaded fuel directly into the high-capacity 3.5-litre fuel tank, check the engine oil dipstick periodically, and ride. This drastically simplifies ownership and eliminates the common two-stroke risk of accidentally destroying an engine by running unmixed fuel.

A: Because it is a highly refined 4-stroke engine rather than a fragile 2-stroke, ongoing maintenance on the ORF 110cc is incredibly straightforward and highly economical. There are no delicate power-valves to clean, and spark plugs last significantly longer. The primary maintenance routine boils down to four simple steps that any parent can easily manage:
