Spark IT Grid-O Step 2 D.60 Titanium Link Pipe & Silencer Yamaha YZR R1 15-26

COMPATIBLE WITH PASSENGER FOOTRESTS

Spark has developed a comprehensive range of 3/4 and full racing exhaust systems for Japanese supersport motorcycles, designed to maximise performance while accommodating different aesthetic preferences and circuit noise regulations.

Different silencer options are available to meet varying noise requirements, without the need for dB killers.

Silencer Options

• Force / Force Evo – designed for the 102 dB limit used by the French Championship and Endurance World Championship

• Konix Evo – designed for 107 dB

• Moto-GP / Grid-O – intended for applications above the stated dB limits

3/4 Racing Systems

The 3/4 system uses a 2-into-1 collector to replace the catalytic converter and silencer while retaining the original manifold. Collectors are available in AISI 304 stainless steel or titanium.

Two configurations are offered:

• D.54 – optimised for 2015–2019 MY, allowing lower noise levels

• D.60 – optimised for 2020–2023 MY, with a 60 mm silencer inlet

Available configurations:

• GYA8828T – D.54 2-into-1 collector + Force

• GYA8879T – D.60 2-into-1 collector + Moto-GP

• GYA8858T – D.60 2-into-1 collector + Grid-O

• GYA8859T – D.60 2-into-1 collector + Force Evo

• GYA8882T – D.60 2-into-1 collector + Force

• GYA8883T – D.60 2-into-1 collector + Konix

Full Racing Systems

Spark's full systems are the top-range option, developed alongside teams competing in major international championships, including the Endurance World Championship.

Collector dimensions, pipe geometry, segments and cones have been developed through extensive dyno testing to optimise torque, performance and reliability. Visible welds provide an authentic racing appearance while serving a functional purpose.

The latest manifold configuration features CNC-machined bushes on the couplings, improving both performance and technical construction.

Available configurations:

• GYA8881T – D.65 stainless-steel collector + Force Evo

• GYA8880T – D.65 titanium collector + Konix Evo

• GYA8850T – D.65 titanium collector + Moto-GP

• GYA8871T – D.65 titanium collector + Grid-O

EWC Full Titanium System

Spark's EWC specification combines a D.65 full titanium system with a Force Evo silencer and was developed for use in the Endurance World Championship.

• GYA8894T – D.65 complete full titanium system + Force Evo
