Italian specialist manufacturer G.P.R. Exhaust Systems has developed several upgrade replacement options for Yamaha's Tenere 700 with the homologated, stainless steel DUAL line as the 'stand-out'.
In line with the Milan based manufacturer's ambitious project to achieve carbon free "zero impact" production by 2023, some 99% of the weight of the DUAL is made from recyclable and end-of-life disposable materials such as common steel scrap.
"All manufacturers need to take their responsibilities seriously," says owner Mauro Orlandi, "and doing so doesn't mean that great performance and looks have to be compromised.
"The aesthetics of the DUAL are perfectly adapted to the classic ADV styling of the Tenere, with an excellent compromise between the classic aesthetics and our innovative technical solutions such as the double outlet with dB killer grill protection (part of the new Euro 4 standards) and the external lacing design, something that has been very difficult to achieve from the mechanical point of view."
The exhaust is much lighter than the original at just 1.6 kg and totally made of 304 stainless steel, including the installation fittings. Mauro says that the sound is "full and deep, but within the new homologation limits. It improves performance on the whole curve, especially from the middle up, with a maximum increase of +3.5 Cv (valve flow coefficient), excellent torque and peak performance at 8,865 rpm."
