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

after thousands of miles.

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.

Paid for new, received used.
Size: 9.5 Wide, Color: Cognac, Size: 9.5 Wide, Color: Cognac
Arrived dirty as if someone whore it for more than a few days. Maybe I was mistaken, but I saw nothing about “previously used” on the Amazon page. Returned it. I would suggest that the company use quality control when it comes to shipping. The shoes seem find otherwise. I ordered 9.5 and it was just a bit tight. If I reorder I will go for size 10.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
