EDR Yamaha R1 Velocity Stacks - R1/R1S/R1M - 2015-2019

I was wondering if these would as good as EDR said they were. I’ve always wanted to buy stacks for my 15 R1. So when EDR finally made them for my bike, I bought them with the incentive that they will add some power. Install was easy. And I rode expecting not to feel anything noticeable, but I was wrong. It does have that “hang on tight or the bike will go on without you” feel which was a great feeling to have. These stacks are a must have. Just awesome.
