The Complete Sur-Ron Ultra Bee Upgrade Guide

The Ultra Bee is a serious step up from the Light Bee — more power, more bike, and a bigger appetite for upgrades. That extra capability is exactly why build order matters even more here. Throw power at an Ultra Bee that isn't set up to handle and stop, and you've built something fast in a straight line but scary everywhere else. The riders who get it right follow a ladder: make the bike fit you and respond first, sort handling second, and add power last — when the chassis can actually use it. Here's how to climb that ladder so every upgrade pulls its weight.

Stage 1: Must-Have First Upgrades

Start with the cheap, high-impact mods that make the Ultra Bee fit you and behave like a real dirt bike. These are the consensus first upgrades — simple to install and immediately noticeable:

• Bars & risers. Wider bars on risers open up the cockpit, add leverage, and make standing and attacking terrain natural.
• Wide footpegs + brace. Big platform pegs give you grip and control; a brace stiffens the mount so they don't flex when you load them hard.
• Grips. Quality lock-on grips cut vibration and hand fatigue on long days.
• Sintered brake pads. The best stopping upgrade you can make before touching calipers — more bite, less fade as heat builds.
• Gripper seat cover. Keeps you planted under the Ultra Bee's stronger acceleration and braking instead of sliding around.
• Sprocket & chain. Re-gearing is the cheapest tuning change there is — dial in snap for tight trails or top speed for open ground.

Done together, these transform the ride before you've spent real money. We bundled the consensus picks into the Must-Have First Upgrades – Sur-Ron Ultra Bee collection. Add 2 or more items from the kit and save 7% on the whole kit.

Stage 2: Handling

The Ultra Bee makes more power than the Light Bee, which means the chassis has more to manage. Handling upgrades are what turn that power into confidence:

• Suspension (forks & shocks). Proper moto forks and a quality rear shock are the upgrade riders say changes everything — better control, less fatigue, and the ability to carry speed through chop and landings.
• Brakes. When sintered pads reach their limit, step up to a bigger rotor, braided lines, and a stronger caliper for consistent, fade-free stopping at speed.
• Wheels. Stronger hubs and spokes take abuse, and a supermoto wheel set opens up pavement riding if that's part of your plan.

This is the stage that earns the right to add power. Build it from the Stage 2 – Handling Upgrades – Sur-Ron Ultra Bee collection.

Stage 3: Power

Power comes last — because speed you can't control or stop isn't fast, it's dangerous. The Ultra Bee already brings strong output, so when you go further, do it in this order:

• Controller first. The controller sets how much current reaches the motor. A performance controller is the biggest gain per dollar — more torque, more top speed, and app tuning for throttle response, power curves, and ride modes.
• Battery second. A stronger controller pulls harder than a stock pack wants to deliver. A higher-discharge, higher-capacity pack feeds that power with less sag and adds range. If the bike feels strong but fades, the battery is the bottleneck.
• Motor last. A bigger motor raises the ceiling once controller, battery, and gearing are dialed. Earlier than that and you just overwhelm the rest of the bike.

The same power logic applies across the Sur-Ron platform — see our deep dive on how to make your Sur-Ron faster. When you're ready, shop the Stage 3 – Power Upgrades – Sur-Ron Ultra Bee collection.

FAQ

What should I upgrade first on an Ultra Bee? Bars, pegs, grips, sintered pads, a gripper seat, and gearing. They make the bike fit you and respond properly before you spend on power.

Do I need new brakes if I add power? Yes. More speed demands more stopping power. Sintered pads are the baseline; a full brake upgrade is cheap insurance once you add real output.

The Ultra Bee is already fast — do I even need Stage 3? Only if you want more. Plenty of riders are happy through Stage 2. If you do chase power, do controller and battery before motor.

Controller or motor first? Controller. It's the biggest gain per dollar and unlocks tuning. The motor is the last step, not the first.

How much can I save buying a kit? Add 2 or more items from any stage kit and you save 7% on the kit.
