300 XC TPI 2021
300 XC TPI 2021 for Sale at Moorooka KTM in Moorooka, QLD | Specifications and Review Information
UNRIVALED POWER-TO-WEIGHT RATIO
Take the unrelenting ferocity of an SX bike, add a few extra horsepower and torque, a longer-range fuel tank and an 18" rear wheel to accommodate more rubber, and you're well-armed to dominate the dirt. In a nutshell, the KTM 300 XC TPI is arguably the most accomplished cross-country racer available.
CYLINDER
This compact cylinder with a 72 mm bore features a cutting-edge power valve unit with a sophisticated mechanism for the lateral support exhaust ports. Matched to a twin-component cylinder head, it is KTM’s secret to all-round grunt. The layout of the water jackets in the cylinder and head guarantees efficient heat dissipation when the going gets tough.
CRANKCASES AND ENGINE COVERS
These die-cast crankcases allow the implementation of a balancer shaft. So your ride will be as relaxed as it is rapid. Plus, your new favourite engine will keep looking as fresh as the day you bought it: its engine covers feature a smart surface structure in order to reduce the wear caused by the rider’s boots.
TRANSMISSION
A robust 6-speed semi-close transmission, its gear ratios perfectly in sync with the 300’s power band. An advanced 'No Dirt' gear shift lever design prevents mud and sand from jamming the joint of the lever and guarantees trouble-free shifting.
BALANCER SHAFT
Say goodbye to numb feet and hands. This engine design allows the implementation of a lateral balancer shaft in order to keep the vibrations to a minimum. You know what that means: more comfort, less fatigue, more racing.
CLUTCH
The KTM 300 XC employs the KTM-developed DDS clutch (damped diaphragm steel) with a robust steel basket, extremely heat resistant clutch plates and new, nitrated steel liners reducing the wear. This clever design employs a diaphragm spring instead of the usual coil springs, making for considerably easier clutch action. A diaphragm spring also leaves sufficient space for a damping system to be integrated into the clutch hub. The goal is traction, but durability is as well. Light operation and telepathic amounts of control are standard with this hydraulic Brembo actuated clutch.
CARBURETOR
The KTM 300 XC is fitted with a MIKUNI TMX carburetor. This 38 mm flat slide carb lives to provide smooth and controllable power all the way up to the rev limitation. With a new intake manifold the carburetor is turned 7° in order to reduce the overflow of fuel. And it's less sensitive to different altitudes and temperatures, so you can pin it wherever, whenever.
IGNITION
All 2-stroke models feature a new CDI control unit with an advanced hardware which improves the starting behaviour of the engine. The ignition curves remain unchanged.
THROTTLE BODY
The TPI engine is fitted with a redesigned 39 mm throttle body made by Dell'Orto. The airflow is regulated by a butterfly connected with a twin-cable throttle cam, which is operated by the handlebar throttle assembly. A throttle position sensor provides airflow data to the control unit. For 2020 the idle system was reworked allowing the idle speed to be set more precisely via the bypass screw. Also, the cold start system is improved for a better supply of extra air when opening a bypass. Oil supplied by the electronically controlled oil pump via an oil intake tube is mixed with the incoming air to lubricate the moving engine parts.
ENGINE MANAGEMENT SYSTEM
The Engine Management System (EMS) of the TPI models features a control unit located below the seat. The control unit determines the ignition timing and the amount of fuel to inject is based on several sensor readings such as intake and ambient air pressure, throttle position, oil and water temperature. Thanks to altitude and temperature compensation the hassle and time of jetting a 2-stroke is no more.
COOLING
KTM’s proven cooling system routes the coolant from the cylinder head through the frame triangle, directly to aluminium radiators made by WP. Thanks to flow optimised 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
The engineers meticulously tuned the resonator chamber for maximum torque and power, so this screamer is as tough as it is strong.
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 aluminium engine head stays (the connection between cylinder head and frame) contribute to 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 aluminium, which tiptoes the scales at less than 2 pounds.
SWINGARM
The cast aluminium design offers low weight and a perfect flex behaviour. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It’s better looking too.
WHEELS
The 300 XC is fitted with lightweight, CNC-machined hubs, high-end Giant rims and black spokes with lightweight aluminium nipples providing maximum stability at minimum weight. The latest Dunlop Geomax AT81 tires guarantee perfect traction and outstanding performance.
FRONT SUSPENSION
The lightweight WP AER 48 front fork, a 48mm 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 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 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 shock absorber has been developed with the entire frame and swingarm architecture in mind, including the linkage and the WP AER 48 front fork. 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 setup and its WP colour scheme lets everyone know you have excellent taste in suspension.
TRIPLE CLAMP
Top quality, CNC machined triple clamps have been a KTM trademark for years to ensure precise handling. The rubber damped handlebar fixation allows for two positions and an hourmeter is fitted in order to let the rider know it's time for a service.
BRAKES
These high-tech Brembo babies are combined with lightweight wave discs. You couldn't brake any harder, better, faster or stronger.
FUEL TANK
All XC 2-stroke models have new lightweight polyethylene tanks fitted with an integrated fuel pump system and capacity of 2.6 gallons. Inside threads on the filler cap make for an easy and reliable closure.
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.
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 smudging up the pegs, even when digging in deep ruts. Looking for a higher riding position? Then just mount the footpegs of the 2018 EXC models, which are 6mm higher than the SX versions.
DECALS
A new, tailor-made kit and a Factory orange frame. Because in this sport, champs deserve to look the part regardless of the dirt.
