Description
StringerStacks by SRS is a 3D-printed replacement R1 velocity stack kit for the Yamaha R1 & R1M 2015 onwards and are printed from fuel and contaminant-resistant materials.
This R1 Velocity Stack kit for the R1 2015 onwards requires no ‘dremeling’ or destroying of your existing oem stacks, Stringer Stacks come complete and ready to install, we just reuse the aluminium bars from your oem stacks which easily unclip from the oem stacks and clip into our custom printed stacks.
With shorter lower bellmouths these stacks feed the R1’s appetite for big air, and when the upper stacks lift it gives great increases in midrange and top end power.
The installation is a DIY job, to get the most out of the stacks we advise either a custom dyno map, or the use of FTecu and ActiveTune to correct the fueling to get the biggest gains from your bike.
These R1 velocity stacks are available for the following bikes
- Yamaha R1 2015-2019
- Yamaha R1 2020-2024
2CR, BX4, B3L Stock and GYTR motor
