This doesn't look like an HD because we do not work on cruisers. There just isn't enough time in the day so changes have been made. ONLY LATE MODEL Sport bikes are upgraded at this time.
STPI Cycles was built by Shane — a sport bike rider and mechanic who got tired of watching performance shops treat sport bikes like an afterthought. What started as a passion for making machines go faster turned into a dedicated shop in Porter, Texas, where sport bikes aren't just accepted — they're all we do.
We specialize exclusively in sport bikes, which makes us better at them. No cruisers, no dual-sports, no distractions. Every tool we've invested in, every skill we've developed, and every hour of experience in this shop has been focused on inline fours, twins, and the sport bike riders who push them. That focus shows up in the quality of every build that leaves here.
The race credentials aren't just for show. Shane runs a grudge bike and competes with an XDA Real Street race bike — which means when we build your motor, set up your suspension, or tune your bike on the dyno, we're applying knowledge earned on the track, not just the shop floor.
STPI Cycles is the right shop if you're serious about your machine — street riders, track day regulars, and racers who need a build they can trust when it matters.
