R46 Rear Shock
EXCEPTIONAL RESPONSIVENESS
Ultimate Suspension Tuning Fully tunable valving on compression and rebound, with spring rates matched to rider weight and riding type. Adapt your suspension setup for different types of rides, enhancing overall riding experience.
TUNING WITHOUT COMPROMISE
LSC (Low Speed Compression) Superior pressure balance and frequency response providing the ultimate overall responsiveness and performance for riders.
Optional DSC note: We're fine tuning the DSC now and it will be available in a couple months (likely early 2025). The DSC will offer a wider adjustment range than the LSC. LSC and DSC fit in the same cavity and are cross compatible (with a rebuild). Both will be offered as service parts. (ie. if you purchase the current LSC now, it can be serviced and tuned to add DSC later. More details to follow)
Made For You Tunable to any rider style and condition. Personalize to rider weight up to 300 lbs (135 kg) with high-tensile steel spring rate options.
BUILT TO LAST

Extremely Easy to Rebuild Fully serviceable design ensures easy rebuilds and custom tuning.
Direct Swap Easy installation, 320 mm length (85 mm stroke) bolts directly onto a stock Ultra Bee.
Lightweight Weighs only 3.9 lbs (1.76 kg) plus spring.
STOCK ULTRA BEE TRIANGLE FITMENT:
For guaranteed fitment on your Surron Ultra Bee, we highly recommend the Sirris rear triangle installed during the shock installation procedure.
The Sirris Shock is designed to offer the maximum possible piston size and still fit within the stock linkage. Tolerances on each stock Ultra Bee vary. Light contact between spring OD and stock triangle may occur. We highly recommend our higher clearance triangle to prevent this.
WARNING: Some aftermarket triangle links may have significant interference that could damage the shock and/or triangle. It’s important to check clearance as you assemble and cycle the suspension. Do not install Sirris shock if any interference is detected. Failure to properly install the shock with proper triangle can lead to a loss of control of the motorcycle which can result in SERIOUS INJURY OR DEATH.

As the title states, it’s perfect. A lil bulky and odd shaped for no reason but it’s still perfect. Also it does fit the version 1 eride pro key. You just have to melt the plastic off. Under the soft plastic there is a harder plastic.
The black plastic body kit is perfect. They came wrapped up to prevent scratches and boxed in a cardboard box to prevent bending. Shipping was only a couple days and the price is competitve and a little lower than other sites. Adding that the black kit is out of stock everywhere else.
These brakes perform so much better than the original stock brakes on the Talaria XXX Pro. The difference is amazing. Now the Talaria has reliable positive brake control with so much better grip than before.
We picked the gold color, which looks great on the black bike. Highly recommended if you have the budget.
TB Electric has been outstanding--customer service that's fast, friendly, and genuinely helpful. Their very responsive to email, and their YouTube channel is packed with clear, practical insights and honest product breakdowns that make choosing the right setup a breeze. The fun giveaways are a great touch and really show their commitment to promoting the e-moto industry and also to building long-term relationships with customers, not just quick sales. Every interaction feels like I'm dealing with pros who care, yet personal, and it's obvious they truly know their stuff. I highly recommend TB Electric and encourage fellow riders to shop with them -- you'll be in great hands!
