PRO GuIDe Replacement YZF250/450 air filter and 'PowerFlow' kit Twin Air has a new replacement for the OE air filter on the 2019 Yamaha YZF250 and 2018 and up YZF450, with a specially developed 'PowerFlow' kit aluminium cage and sealing ring for more airflow. The cage is easy to install, and the company says that it "provides improved performance and protection for the engine". The company also offers dust covers, rain covers and GP covers, all available for extra protection during extreme weather conditions. A twin-layer, reticulated polyester foam filter (available dry or pre-oiled) that was originally developed for the Yamaha MXGP team solves the design flaws inherent in the OE design. Yamaha’s flat-style air filter rests directly on the backfire screen of Yamaha’s downdraft intake system. The constant vibration of the air filter sucks the air filter oil downward into the intake tract, eventually allowing dirt through the foam as it dries out. Plus, the hole where the external cage’s pin goes through is not reinforced. Under the pulsing of the filter, the foam tears around the pin, creating a potential leak. The Twin Air design is a 22 mm-thick filter with a large grommet that supports the filter, stopping it from rattling against the backfire screen, and a plastic "top-hat" spacer in the centre of the air filter that lifts it 11 mm above the wire backfire screen to improve airflow. Twin Air’s central grommet eliminates the tearing of the foam at the pin and supports the filter better – reducing the risk of top end damage.

Several technical aspects have been improved and it is now certified to the harmonised regulation pr EN17092. It is suitable for use in all four seasons thanks to the three-layer structure and available in two colours in sizes from S to 4XL. Under the outer polyester shell, assisted by ripstop reinforcements on the most abrasion vulnerable zones, are two layers, which can be worn together or separately: a waterproof layer (Humax), tested to a water column rating of 10,000 mm, and a second layer, which is thermal. Ventilation is by means of the Fidlock system (magnetic flap closure) for the two air intakes on the chest and five zippered openings positioned along the airflow. The improvements also involve the fit adjustments and the pockets. The 'Titanium_R' has Level 2 protectors for shoulders and elbows and is ready to accommodate an optional back protector. Two colour options are available, black and ice grey. INTERNATIONAL DEALER NEWS - APRIL/MAY 2019 HEVIK Brescia (BS), ITALY Tel: [phone] [email protected] www.hevik.com www.idnmag.com
