What is involved into such a build? Is it comparable to an SR? Can you run pump fuel? All of those questions and more will be answered in this show. Keefer will also break down what Pro Circuit can do to your suspension and how you can get more comfort as well as hold up within your KX450 SHOWA suspension. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/rocky-mountain-atv-mc-keefer-tested-8146/episodes/show-473-pro-circuit-kx450-stage-one-build/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/rocky-mountain-atv-mc-keefer-tested-8146/show-473-pro-circuit-kx450-stage-one-build.md` — Read the agent-friendly Markdown representation of this episode resource.
