StringerStacks Velocity Stack kit – R1 2015 onwards 2CR, BX4, B3L


Custom printed R1 2015 onwards Velocity Stack kit


StringerStacks are 3D printed replacement stack kits for the Yamaha R1 & R1M 2015 onwards and are printed from fuel and contaminant-resistant materials.

These stacks require 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.

Thie 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.
