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.

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.

I rarely write reviews. This thing is stout and solid AF do yourself a favor and grab one
also fits over a direct mount warp 9 stem (wider than OEM). So when replacing stem you’ll need a wider mount anyhow. Plastic ones are 40 bucks. But Why would you do that ? when you can spend a bit extra and have an aluminum CNC mount that is indestructible. Also come with a thick piece of glass to cover screen side. No brainer. Fit on SR
I thought it would come with the front and the rear because it showed the fron and the bakx in the picture. but it only came with the rear and with no tire rods.
These were so easy to install that I thought i did it wrong until I turned the light on from the bike. These are the perfect upgrade to the stock light
My order was filled promptly and accurately, and was shipped in a timely manner. No complaints there. However after receiving my order, I had a couple follow up questions. I called several times and always got a recording- no one ever answered. I left a message stating who I was and that I had a couple of questions about my order. No one has ever called me back.
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.
