New exhausts by Arrow
Proving their all-round design and manufacturing capabilities, here are three very different kinds of exhaust systems for three very different kinds of motorcycles by Arrow Special Parts from near Perugia in Italy.
First of all, going to their impressive race heritage and credentials, it is a difficult task to improve on a bike that has just won the WBK, but in the case of the impressive 2016 Kawasaki ZX10R, that is exactly what Arrow say they have done.
Arrow’s R&D department have come up with no less than 11 different new (street legal and racing) exhaust systems and four competition racing kits. All slip-on silencers can be installed on original headers, removing the OE catalytic converter, thanks to a model-specific mid-pipe design.
Arrow say the dyno tests results are excellent - the power on the rear wheel, with the original exhaust, is around 185hp, which increases to around 186hp with the Arrow slip-ons and reaches 192hp (with a "great improvement" in torque at low and medium engine range) with the "half system" made by the silencers and the link pipe, removing the OE catalytic converter.
At the other end of the motorcycle spectrum, 'Urban' is a new system for Maxi-Scooters. Offered with new materials and optional catalytic converter, Arrow say that the 'Urban' is a "giant step in innovation", incorporating a "heap of new features".
Those features include a shorter silencer with Superbike 'Race-Tech' style diamond shape, completely re-engineered interiors with a new silencing system, swingarm mounts that are welded to the silencer body, eliminating the adapting plate and improving durability, and a "Racing" style header with optional catalytic converter.
Available in stainless steel with black painted finish or in aluminium, with clear or "dark" finish (and rear end cap with matt black finish), Arrow say the street legal system with a removable dB-Killer delivers reduced weight and improved performance.
If the ZX10R is at one end of the motorcycle spectrum, and with the generation of large displacement Maxi-Scooters at the other, then Metric Cruisers are right in the mid-market.
Arrow's new 'Rebel' exhausts for Japanese cruisers is their first entry into an exhaust market that rewards style as much as performance.
Street legal, Arrow say the new designs deliver up to a 40 percent weight reduction and up to a 10 percent increase in power.
They are available for Kawasaki Vulcan S650 2014/2015 and Yamaha XV (Bolt) 950 / 950R 2014/2015, with new model applications to follow, and work is in progress to extend the range to other bikes.
