Italian exhaust manufacturer MIVV has updated the application list for its popular 'Ghibli' silencer and added a new 'GP Pro' design for the Kawasaki Z900RS.
The company says that the Z900RS is "the perfect example of a “new classic bike” - no longer a mere replica of models that have left a mark on the motorcycling world, but a homage to the cornerstone Z1, the first 4-cyclinder bike produced by Kawasaki and the first Superbike of that era".
Sensitive to being consistent with that design paradigm, MIVV says its new 'GP Pro' is an evolution of the popular race-derived GP exhaust, with welding "executed with a semi-artisanal TIG process, the precision fit and convincing sound with a removable, protective grille in the end cap concealing the internal dB-Killer".
Offered in three versions - black painted stainless steel, "pearly" effect titanium and gloss finish carbon. Those looking for more of a "Classic Look" can choose the 'Ghibli' - a stainless steel, fully TIG welded slip-on with an extractable dB-Killer and "unique and robust" sound.
The 'Ghibli' is quoted as delivering torque and power improvements in the 5,000 to 7,000 rpm range with an increase to 89.8 Nm and 97.3 hp respectively, with a -0.5 kg weight saving.
The 'GP Pro' is said to boost power output to 97.4 hp, with particular gains where it is needed most.
Also seen here, a new full system for the GTS 300 Vespa adds to the already offered 'Urban' stainless steel silencer options. The complete kit includes a stainless steel manifold, fitted with a Delta Race tailpipe. Usually fitted to sports and naked bikes, "it appears surprisingly at home on this scooter" and is compatible with all GTS 300 models produced from 2006 onwards (Euro 3 and Euro 4) thanks to the optional Cat.
It is said to enhance both power and torque, especially at low revs, with a significant -3.4 kg weight saving compared to the OE system, the main improvement being above all the power at low revs. Weight savings are also significant, recording -3.4 kg compared to the factory item.
The Delta Race tailpipe design sees the shape transition from conical to hexagonal and features carbon end caps, with double riveted perimeter bracket retaining band, solid machined inlet bush to ensure maximum coupling precision and an aerodynamically tuned main body. It is available in brushed stainless steel (INOX) with a "pearl" effect and a "Black Moon" effect finish that is obtained by using a ceramic-based paint for a "particularly aggressive" look.
