BC Build / Triumph Speed 400 – DGR Winner. Bolt-On Style.
When Southern California Triumph handed us the keys to the 2025 Distinguished Gentleman’s Ride giveaway bike—a bone-stock Triumph Speed 400—we saw more than just potential. We saw a platform begging for transformation. Light, agile, and dripping with British heritage, the Speed 400 already came with the right DNA. But with the right weekend upgrades, we knew it could do more than just blend in.
This wasn’t a ground-up build. It was a rider-first refresh—a clean, confident reminder that customization doesn’t require a shop full of tools or a stripped-down frame. It takes vision. It takes the right parts. It takes bolt-ons that deliver performance without compromising daily rideability.
5 Bolt-On Upgrades That Transformed the Speed 400
Slash Cut Exhaust Tip | Brushed Finish
Stock gets the job done—but this tip gets the job noticed. Our brushed stainless Slash Cut Exhaust Tip pares down the look, lightens the load, and cranks up the tone. With a deeper, throatier growl that plays nice with the factory cat, it bolts up in minutes and doesn’t require tuning. Just more attitude, less bulk.
British Customs Retro Handlebar Kit
Rider control starts with the cockpit. This mandrel-bent 304 stainless bar kit is a throwback to the café era, tailored for modern comfort. With improved ergonomics and no need to mess with cable lengths, it puts you in a ready-to-ride position—available in polished or semi-gloss black to match your build’s personality.
BC Universal Bar End Mirror Kit
Our hollow bar-end mirror mounts are precision-machined from 6061-T6 aluminum, finished in anodized black, and built to stay planted through spirited canyon rides or sketchy commutes. Clean, functional, and versatile—exactly what you want from mirrors that pull double duty in style and safety.
Screw-In Mirror Hole Caps (Standard + Reverse Thread)
Don’t leave your stock mirror threads exposed. These CNC-machined caps are light, low-profile, and anodized to blend into the controls. Designed specifically for Triumph’s mixed-thread bars, they seal up the look in seconds.
CRG Blindsight Mirror
Compact and clean, the CRG Blindsight is the final detail that ties the bar setup together. At just 2 inches wide, it offers wide-angle visibility without stealing the spotlight. Mounted via a rubber-insert system that soaks up vibration, it's small in stature but big in impact.
The Distinguished Gentleman’s Ride Connection
This isn’t just a parts list—it’s a tribute. The Distinguished Gentleman’s Ride unites motorcyclists worldwide to support men’s health. We built this Speed 400 to match that mission: simple, stylish, and purpose-driven. It's a reminder that personal expression and good causes can ride in tandem.
Your Speed 400, Your Way
Customization doesn’t have to be complicated. These five upgrades install with basic tools and a bit of garage time. No wire cutting. No stress. Just bolt-on style with real-world performance.
Because that’s what British Customs stands for:
Easy to Install.
Your Bike, Your Way.
Upgrade Without the Guesswork.
