Manufacturer reference: GSU8005D —Spark Off-Road Dark Style (Full system), competition exhaust system.
This full Spark Off-Road system is specially developed to meet the extreme demands of motocross and enduro. It replaces the entire original exhaust system to optimise gas flow and engine performance. This system is exclusively for use on closed circuits or private land and does not have road approval.
Finish: stainless steel collector (AISI 304 stainless steel) + side silencer in "Dark Style" finish (black stainless steel).
Compatible models:Suzuki RM-Z 450 (2015-2017).
Specificity: reinforced design to withstand shocks and stresses of off-road riding, with an integration designed to closely follow the lines of the motorcycle.
Approval: not approved (not compliant with FFM noise standards for motocross/enduro in France due to a volume of 113.5 dB, a level far too high to pass sound meter checks).
Sound level: 113.5 dB (raw measurement).
Soundproofing: dB killer not included (sold separately, adding reference G9925 reduces the volume to approximately 111.5 dB).
On the dirt track, this full system allows for total release of exhaust gas flow, ensuring an increase in power and torque, crucial elements for quick acceleration out of corners or in technical sections. The specific design of the Off-Road range also aims to limit the exposure of the silencer during falls.
(Note: Installing this full racing system requires adjustment of the injection to optimise the air/fuel ratio and ensure the mechanical reliability of the machine).
