I Built The PERFECT Electric Pit Bike | ETM RTR Sport Upgrades
The Build
The ETM RTR Sport is already one of the best electric pit bikes you can buy — but stock is just the starting point. In this build, we took a Sport and turned it into something you'd actually stop and stare at. Every part is available in The Watts Shop, so if you like what you see, you can do the exact same thing to yours.
The Upgrades
Mint Body Kit The stock RTR Sport looks clean, but a fresh body kit changes everything. The mint colorway makes this bike impossible to miss at the track. Bolt-on fitment, no cutting or modification needed.
RLV Gold Chain An RLV gold chain isn't just for looks — it's a higher-quality chain that runs smoother and lasts longer than stock. And it looks absolutely dialed next to the mint panels.
Custom Decals We ran a custom decal set to tie the whole build together. Your name, your colors, your bike. These are the details that separate a stock bike from YOUR bike.
Custom Handmade Seat The stock seat is fine. This seat is not fine — it's a work of art. Custom foam, custom cover, built specifically for this build. Comfort upgrade and a head-turner at the same time.
Oil Slick Adjustable Forks The oil slick finish on these forks catches light every time the bike moves. Fully adjustable so you can dial in the suspension feel for your rider's weight and riding style.
Custom Handlebars Custom bars let you set the exact width and rise for your riding position. Better control, better ergonomics, and they look the part on a build like this.
12" Supermoto Mags This is the upgrade that transforms the whole feel of the bike. Supermoto wheels open up a completely different riding experience — tighter turns, better grip on pavement, and a stance that looks like it belongs on a full-size machine.
Why Upgrade Your RTR Sport?
The ETM RTR Sport is already a serious electric pit bike right out of the box. So why upgrade it?
Because it's YOUR bike. Stock is for everyone. A custom build is for you.
Beyond the looks, upgrades like adjustable forks and supermoto wheels genuinely change how the bike performs and handles. You're not just making it prettier — you're making it better. And when your kid rolls up to the track on something that looks this good, they're going to want to ride it every single day.
The RTR Sport is also the perfect platform for a build like this because the quality of the base bike is already there. You're not trying to fix a bad bike with parts — you're starting with something great and making it exceptional.
