After months of real-world testing and rider feedback, this Ultra Bee brake conversion fits these bikes exceptionally well, coasts clean for wheelies, and offers outstanding modulation.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eChoose Your Caliper: OEM or Replica\u003c\/strong\u003e\u003cbr\u003eThis kit comes with your choice of two caliper options so you can match your budget and your build:\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFull OEM Ultra Bee Brake System\u003c\/strong\u003e – The genuine Ultra Bee caliper and brake system.

Compared to the OEM system, the replica is slightly less powerful with a bit less back pressure, so lever feel is marginally softer, and overall build quality is a step below the genuine unit.
