Il set di ruote classe Supermini da 19/16” è composto da mozzi Faster USA ricavati dal pieno con raggi Bulldog in acciaio inossidabile e cerchi Excel. I pignoni di trasmissione Renthal e la catena DID sono della serie 428 e gli ingranaggi standard 14/49 funzionano per la maggior parte delle piste da corsa grazie alla scatola di trasferimento a ingranaggi.
Una piastra paramotore in alluminio DirtFirst protegge il motore consentendo comunque il massimo flusso d’aria all’involucro del motore. Vengono utilizzati un tubo dell’acceleratore in alluminio billet G2 ergonomico e inserti per l’eliminazione del gioco dell’acceleratore, nonché impugnature Renthal 827 FatBar e Renthal. Le pedane in titanio Apex Raptor sono leggere e offrono una presa superiore. Il dispositivo Holeshot Works Connection è un must per le partenze MX, mentre il rivestimento della sella con pinza plissettata Red Label e la grafica della squadra completano il pacchetto.

PRESS RELEASE
2024 Husqvarna EE18 Rockstar Edition
DirtFirst Racing and Hollywood Movie Bikes have once again teamed up to build a bike that the big factories have been dragging their feet on. Husqvarna currently has no electric bikes in their model lineup larger than a 50cc gas equivalent, and with a growing number of battery bikes from other manufacturers hitting the market, one would think the brand known for some cutting-edge bike design might want to get in the mix. Maybe it’s a lithium and cobalt supply issue. Maybe they are waiting for the charging infrastructure to be ironed out. Maybe it’s a result of CEO Stefan Pierer going all in on the techno-optimism of E-Fuels replacing gasoline, a pipe dream in which we can keep using existing engine designs and run them with fuel made from refining captured carbon with solar power. Whatever the reason, the company’s stagnation has allowed DirtFirst Racing to put out an electric MX bike model that Husqvarna could be building now.
Based on the DirtFirst team’s KTM Freeride Supermini race bikes, the EE18 uses all the innovations and works parts the team has developed during the last two years of participation in various racing disciplines. These bikes are aimed at 12-16 year old riders that want to gain vital experience for the coming wave of full-size electric MX bikes. With a race-winning pedigree and proven reliability, the EE18 fills a gap in the motorcycle industry’s electric MX lineup.
The heart of the EE18 is KTM’s 18kw brushless electric motor, which is energized by a 3.9kwh lithium-ion battery pack and managed by an integrated motor controller. This powertrain has proven to be very reliable and simple to maintain. The smooth power delivery and water cooling allows it to outperform even the most highly modified Surrons and Talarias. To enable the EE18 to be raced at its maximum output in hot conditions, DirtFirst has added 30% more coolant capacity, as well as mounting 3” diameter cooling fans on the radiators. The fans run off a separate 12v battery and are controlled with a handlebar switch. An LED temperature gauge is mounted in the bar pad, and reads the coolant temp as it exits the motor’s water jacket for maximum accuracy.
The EE18 uses 43mm WP Air Forks, which are lightweight and easily adjustable. Schmidt Performance handles the fork valving and low friction coating. Billet XTrig ROCS triple clamps keep the fork tubes secured, and have a 14mm offset. The RaceTech GS3 rear shock is fully adjustable, and a wide range of springs are readily available off the shelf for different weight riders.
The 19/16” Supermini-class wheel set consists of Faster USA billet hubs with stainless steel Bulldog spokes and Excel rims. The Renthal drive sprockets and DID chain are 428 series and standard 14/49 gearing works for most race tracks due to the geared transfer case.
To stop the 230lb machine, the EE18 is equipped with Brembo brake systems front and rear. These are the same brake components used on the current KTM SXF models. A Galfer 260mm floating front rotor, and 220mm rear rotor are sized perfectly for the bike’s weight.
A DirtFirst aluminum skidplate protects the motor while still allowing maximum airflow to the motor casing. A G2 Ergonomics billet aluminum throttle tube and throttle play eliminator inserts are used, as well as Renthal 827 FatBars and Renthal grips. The Apex Raptor titanium foot pegs are lightweight and offer superior grip. The Works Connection Holeshot Device is a must for MX starts, and the Red Label pleated gripper seat cover and team graphics complete the package.
