350 XC-F - 2019


Model Description

The success story of the 350 XC-F is certainly unrivaled. It has been the bike KTM Factory FMF offroad rider Kailub Russell has used to dominate the GNCC series. Over the years and again for 2019 350 XC-F has gained a lot of performance and torque providing almost as much power as a 450, but with the agility of a 250 – so the basic idea is easily summarized, and has been a concept with success from the start.

The engine of the 350 XC-F features a compact and very light (58.6 lb.) construction. Featuring a new clutch, improved transmission and a re-designed and lighter DOHC cylinder head the engine is stronger than ever before. Lightweight titanium valves and DLC coated finger followers allow for lively but also very strong engine characteristics. Fitted with the latest electronic fuel injection system and electric starter, it has an even wider usable speed range, improved performance and incredibly efficient rideability.

The 350 XC-F has a reworked cylinder head design featuring the same architecture as before but it lost 200 grams of weight. The two overhead camshafts with a friction-optimized super-fine surface, finger followers with a DLC coating are carried over as well as four lightweight titanium valves (intake 36.3mm, exhaust 29.1mm). The flow rate has been maximized for an optimal power band, with outstanding performance across the entire range, which ends at an engine speed of 13,400 rpm. 

In the short cylinder, with a bore of 88mm, is a forged bridged box-type piston made by CP. Its piston crown geometry is adapted perfectly to the high-compression combustion chamber and stands out with its extra rigid structure, combined with a low weight. The compression ratio is at 14:1. Thanks to the low oscillating masses, the engine offers extremely lively characteristics.

The 350 crankshaft features a stiff design and it utilizes a short connecting rod, contributing to the compact and light engine with a dynamic and efficient power delivery. A plain big end bearing features two force-fitted bearing shells run directly on the crank pin. This design is a major prerequisite for the extremely high engine speed levels and the unrivalled maximum power of the 350cc engine. Not only that, it enhances the engine's durability, allowing long crankshaft service intervals – a customer benefit in respect of time, effort and cost.

In order to balance the mass-forces, the 350 XC-F engine uses a multifunctional counter balance shaft, which at the same time drives the water pump and timing chain.

The 350 XC-F is fitted with a unique electric starter as standard, which is well known as a clear advantage when it comes to crunch time in the heat of battle. A strong starter motor made by Mitsuba and the proven starter drive guarantees efficient and reliable starting.

A newly developed DS (diaphragm steel) clutch features a one-piece clutch basket combined with the primary gear made of high-strength billet steel. It guarantees unbeatable reliability and contributes to the narrow engine size due to its compact rivet-less design. It is fitted with extremely heat-resistant steel carrier friction discs which ensure a good disengagement of the clutch. These are pre-tensioned by means of a diaphragm spring, substantially reducing the operating force required to pull the clutch. The Brembo hydraulic system provides easy and precise modulation.

The 350 XC-F uses a new 5-speed transmission made by PANKL RACING SYSTEMS ensuring the highest durability and reliability level. There was no need to change the gear ratios that are perfectly matched to the power delivery of the large displacement engine. 

An advanced "NO DIRT” gear lever design prevents dirt from blocking the joint of the lever and guarantees safe activation of the transmission.

All four-stroke engines are fitted with a gear sensor giving the option of different engine characteristics for each gear.

The state-of-the-art Keihin Engine Management System, with electronic fuel injection, features a new 44mm throttle body, which provides a spontaneous response and maximum performance thanks to its unique injector position. This guarantees excellent atomization of the fuel with the air on its way to the combustion chamber. In addition there are separate systems for cold start and idle adjustment. A reworked throttle cable mount allows for smoother routing of the cables and better access, an improved seal of the MAP sensor (MAP = Manifold-Absolute-Pressure) makes the system even more reliable.

The ECU features new maps adapted to the new exhaust and cylinder head and it regulates the unique traction and launch control. In addition it provides different maps for optimal power characteristics for each gear according to the information received by the gear sensor.
