Please note some products have increased in price due to Import tariffs
Dont wait until summer to order brembo, carbonin or other european brands because the industry closes for the month of August so resupply takes longer

Smooth Velocity stacks for Yamaha R8 from 2008-22
Please note these do not fit the 2006-2007 R6 as they do not have variable stacks
Carbon Smiths 2020+ Aprilia RS660 Velocity Stacks are an amazing upgrade to boost performance on your Aprilia RS660! After several hundred dyno runs, 15 different velocity stack configurations, and 15 gallons of fuel, CarbonSmith has finally finished developing the perfect velocity stack configuration for your RACE TRIM Aprilia RS660! Changing the stock exhaust and OEM air filter allows for much different stoichiometric air/fuel mixture allowing us to change the targeted resonant frequency resulting in MORE POWER!! We found +2 hp gains at multiple spots in the RPM curve with a simple drop in test! More gains are possible with full custom dyno tuning!
THIS KIT INCLUDES A COMBINATION LEFT AND RIGHT VELOCITY STACK DESIGNED FOR OPTIMUM AIR/FUEL MIXTURE ACROSS THE ENTIRE RPM RANGE.
DIMPLE DESIGN CREATES ADDITIONAL TQ AND HP AT HIGH SPEED.
MANUFACTURED WITH NYLON EMBEDDED CARBON FIBER REINFORCED WITH CONTINUOUS CARBON FIBER. THIS MAKES THEM EXTREMELY STRONG, LIGHTWEIGHT, YET FLEXIBLE AND VERY RESISTANT TO HEAT AND CHEMICALS. THESE SHOULD ONLY BE INSTALLED BY A PROFESSIONAL.

I will definitely be contacting HHR for more products in the near future.

Looks like incredible engineered products, both the thumb brake & the rear master cylinder. On the master cylinder, be aware QNIUM use 6mm bolts where as the stock Triumph 675 bolts are 8mm. Not a big deal, just be aware.
