Aggressor Speed Kit // 2010 & Newer Arctic Cat/Yamaha 120

AGGRESSOR SPEED KIT ARCTIC CAT / YAMAHA

This Speed Kit was named for the type of rider you have. If your child is AGGRESSIVE and you need to jump up to the next level in speed and power, we’ve created the AGGRESSOR SPEED KIT for you. Not only will it allow your child to hit the speed they want, it is upgradable to many stages.

Kit Includes: Power Intake Kit which comes with an adjustable main jet to correct the lean fuel condition that 120’s have from the factory, a Velocity Stack to give the engine more air then the restrictive factory air box, and the correct Governor Spring for more RPM’s, a Standard Upgrade Replacement Clutch, Quick Change Hub, #35 Sprocket and Chain.

This kit will typically help you gain 5-9 mph from stock speed.
