2021 KTM 350 XC-F Kailub Russell

Bodywork & Graphics

• DECALS: The KTM 350 XC-F KAILUB RUSSELL features an orange frame that is perfectly matching with its special Red Bull KTM Factory Racing team decals and Kailub's own number #1 on its number plates.

Chassis

• FRAME: The high-tech, lightweight chrome-moly steel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on high torsional rigidity and low longitudinal stiffness. This results in better absorption of the energy created from the front and rear suspension, sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight aluminum engine head stays (the connection between cylinder head and frame) contribute to more precise cornering and a reduced vibration level. The engineers were able to pull off all that, while making their frame 2.2 pounds lighter than that of the lightest competitor on the market. In addition, it is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light subframe made of aluminum, which tips the scales at less than 2 pounds.
• SWINGARM: The cast aluminum design offers low weight and a perfect flex behavior. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It's better looking too.
• WHEELS: The KTM 350 XC-F KAILUB RUSSELL is fitted with high-end Factory wheels. They feature black D.I.D DirtStar rims and fully CNC-machined orange anodized hubs. Together with black spokes and orange anodized aluminum nipples, they guarantee minimal weight at maximal stability so that the rider will feel an increase in handling. The latest Dunlop Geomax AT81 tires guarantee perfect traction and outstanding performance.
• FRONT SUSPENSION: The lightweight WP XACT front fork with AER technology, a 48 mm USD air-sprung fork developed by WP in close collaboration with KTM, is a split fork with separate functions for each leg. That means damping functions are on the right side, whereas the air spring is in the left. This left leg features a 2-chamber system with a capsuled air cartridge to prevent loss of air pressure. Should the outer seal start to leak, the internal cartridge pressure will keep the bike in position. The air spring is easy to adjust to any rider weight via a single air valve. No extra special tools are required; the fork air pump is supplied with the bike. The right fork leg integrates a damping cartridge that tailors to all your damping needs. It can be adjusted to the track conditions and the rider's preferences with a twist of a dial (compression from the top, rebound from the bottom, 30 clicks each). Right off the dealer floor, this fork (with updated internals and reworked damping characteristics) is more comfortable and more sensitive than ever. But you can still hammer the hell out of it.
• REAR SUSPENSION: The WP XACT shock absorber has been developed with the entire frame and swingarm architecture in mind, including the linkage system and the WP XACT front forks. It features machined and black anodized components and is a valuable, high-end product compared to roughcast reservoirs. A new, confidence inspiring setting with improved damping characteristics perfectly matches the front-end set-up and its WP color scheme lets everyone know you have excellent taste in suspension.
• TRIPLE CLAMP: The KTM 350 XC-F KAILUB RUSSELL features Factory triple clamps anodized in orange. The triple clamp has a precisely calculated stiffness and adjustable offset (20 - 22 mm) to match the flex characteristics of the frame and fork. The result is a front end that all works in perfect harmony, contributing positively to the overall handling and stability. The rubber damped handlebar fixation reduces vibration and also allows for some adjustment with two different mounting positions. An hour meter is fitted as standard on the upper triple clamp, keeping the rider informed of the number of hours spent tearing up the track and when the next service is due.
• BRAKES: These high-tech Brembo babies are combined with lightweight Wave brake discs. You couldn't brake any harder, better, faster or stronger.
• FUEL TANK: The KTM 350 XC-F KAILUB RUSSELL is fitted with a large 2.64 gallon polyethylene XC tank with quick-fill option. It come with the standard enduro filler cap but it can be easily converted to the quick-fil IMS System.
• AIRBOX: The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow. The large Twin Air filter is mounted in a stiff cage, which at the same time holds the system in place. This design is so simple, you could still pop a fresh one in with a face full of mud. Without tools. In seconds.

Engine & Exhaust

• ENGINE: Featuring a compact and lightweight (60 lbs) construction, this DOHC (double overhead camshaft) design boasts lightweight titanium valves and Diamond-like Coating (DLC) cam followers allow for lively power across the rev range. Fitted with an FMF muffler, the KTM 350 XC-F KAILUB RUSSELL pumps out big power, but remains as nimble as a smaller machine, making it the perfect middleweight monster.
• CYLINDER HEAD: The cylinder head features two overhead camshafts with friction-optimized cam followers boasting a DLC coating and high-flow ports. Four lightweight titanium valves maximize the flow rate for an optimal power band and outstanding performance across the seemingly endless rev range of 13,400rpm. Lateral brackets made of aluminum allow an efficient fixation of the engine to the frame and contribute to the bike's featherweight feel.
• CRANKSHAFT: The KTM 350 XC-F KAILUB RUSSELL's crankshaft utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big (bottom) end bearing with two force-fitted bearing shells runs directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine's pressurized lubrication. This design is a decisive benefit in terms of the crankshaft service interval, which can be lengthened due to the plain bearing. So just pin it, all day long.
• CRANKCASES AND ENGINE COVERS: The design of the die-cast crankcases allows for minimal weight and a very centralized shaft configuration. This makes the engine short and compact, while contributing to an efficient centralization of masses. The engine covers also feature a solid surface structure, which reduces the wear caused by the rider's boots. This way, your XC-F will keep looking better longer.
• TRANSMISSION: The engine is fitted with a smooth 6-speed semi-close transmission, which features a special surface treatment on the 2nd, 3rd and 4th gears for best reliability. An advanced 'no dirt' gear shift lever design prevents mud and sand from blocking the joint of the lever and guarantees trouble-free shifting. The engine is fitted with a gear position sensor, giving the option of different engine characteristics for each gear.
• ENGINE MANAGEMENT SYSTEM: The state-of-the-art Keihin engine management system with electronic fuel injection features a 44 mm throttle body. Thanks to its unique injector position, the engine's response is instantaneous. And to make life even easier, separate systems for cold starts and idle adjustment await you. The lightweight control unit features a unique traction and launch control system for lightning-quick response when the gate drops and maximum grip thanks to different maps that sync with to the gear you're in. It's also possible to unleash an even more powerful mapping via the handlebar map select switch.
• CYLINDER AND PISTON: Inside the short cylinder, with a bore of 88 mm, thumps a box-type piston made by CP. Its crown geometry is adapted perfectly to the high-compression combustion chamber (14.2:1), where its rigid structure and low weight shine. Thanks to the low oscillating masses, the engine is both snappy and strong.
• BALANCER SHAFT: To balance the mass-forces, the KTM 350 XC-F KAILUB RUSSELL engine uses a multifunctional balancer shaft, which at the same time drives the water pump and timing chain.
• CLUTCH: The DS (diaphragm steel) clutch, literally puts the control back in the hands of the rider. It features a durable, one-piece clutch basket and primary gear, made of high-strength billet steel, guaranteeing unbeatable reliability. It is fitted with extremely heat-resistant steel carrier friction discs, which are pre-tensioned by means of a diaphragm spring, ensuring the most effective disengagement of the clutch. This design substantially reduces the operating force required to pull the clutch and is made even easier with the Brembo hydraulic system.
• E-STARTER: The KTM 350 XC-F KAILUB RUSSELL is fitted with a unique E-starter as standard, which is a clear advantage when it comes to crunch time in the heat of battle. A strong starter motor made by Mitsuba will fire time and time again at the push of a button. Even under extreme conditions, thanks to its more heat resistant O-ring.
• COOLING: KTM's proven cooling system routes the coolant from the cylinder head through the frame triangle, directly to aluminum radiators made by WP. Thanks to flow optimized internal circulation and CFD-calculated ventilation, the system is superbly efficient. In addition, new radiator protections improve heat dissipation. Especially in the mud. They are also integrated into the front part of the shrouds to protect the radiators in a crash.
• EXHAUST: When it comes to power delivery and performance, the exhaust plays a key role. The premium FMF slip-on muffler works perfectly together with the header pipe and its advanced FDH (Flow Design Header) resonator. The exhaust system packs a punch that is hard to beat without compromise to regulatory noise limits.

Ergonomics & Comfort

• HANDLEBAR: KTM engineers sure know how to handle handlebars. This tapered one, made of high-strength aluminum, is fixed in damped rubber mounts and has two different positions. ODI lock-on grips make grip changes easy and do not require any wire or glue to be secured.
• FOOTPEGS: Sophisticated ´No Dirt´ footpegs prevent clogging of the footpeg pivot, even when digging in deep ruts. Looking for a higher riding position? Then just mount the footpegs of the EXC models, which are 6 mm higher than the XC versions.
• SEAT: Ergonomically perfect, the seat has a high foam volume, which offers great comfort and durability, while keeping the weight low.

Software & Electronics

• BATTERY & WIRING HARNESS: A strong lithium ion battery breathes life into the engine and contributes to low vehicle weight. The lightweight battery and wiring harness are centralized in a compartment above the air filter box, allowing the mechanic to remove the subframe without moving the electronics. A happy mechanic is a good mechanic.
• TRACTION CONTROL: TRACTION CONTROL is a highly beneficial feature that guarantees more efficient traction and better control of the bike when accelerating on wet or slippery hard pack surfaces. It can be activated by the handlebar map switch during riding.
• HANDLEBAR MAP SELECT SWITCH: With one touch of a button, the map switch gives the rider the chance to select between a standard map setting and a more aggressive map for loamy, high grip dirt conditions. This is particularly useful for changing track conditions or for riders who are looking for more control as they begin to fatigue.
