We display live inventory for in-stock items. However, due to the vast catalog of products this brand offers, we place orders with our supplier every 2–3 weeks. If an item is out of stock, it will be included in our next order, with arrival typically expected within 3–6 weeks.
Extreme Components is proud to present an additional news for Ducati Panigale V4 / S & Streetfigher V4 / S 2025: the swingarm cover set in Twill Carbon Fiber.
The debut of a double sided swingarm on Ducati V4/S 2025 has offer the chance to challenge ourself once again.
The result is a swingarm cover set, very complex to produce, very protective and with a superb look. Always present is the integrated chain guard in the lower side, introduced from us some years ago in one of our swingarm covers.
As always our parts guarantee the best lightness and resistance thanks to the technologies we use in the production and thanks to our gained experience in the creation of components for the best team of the World Championship.
Our carbon fiber parts are produced through autoclave process, with vacuum technology, using pre-preg carbon fiber (Twill weave) and pressure that can vary from 5 to 8 BAR and temperatures from 60° to 90° according to the product that must be produced.
The lamination is by hand with the aim of carefully choosing the fiber direction and to reach the best result on aesthetic-functional term. In the zones that are more exposed in case of crash we add some carbon kevlar layers to reinforce even more the parts and guarantee even an higher protection of the swingarm.
The finishing is gloss (or matt on request with a price surcharge).

The higher pressure cap stopped my overflow from becoming pressurized and blowing out. I did a combustion gas test on the cooing system and it passed all 3 times, so it made since the factory cap was to low of a rating for serve duty.
The internet provides many options. Not all are good. HHR provides top notch customer service and the best parts available.
quick shipper
awesome customer service
I ordered Avio fiber glass fairing and all necessary brackets for 2023 Yamaha r1. HHR answered all my questions by email and later by phone. The staff I communicated with were knowledgeable, straightforward, helpful, and non-judgmental. I've had been using the products for more than a year, and I have no complaints and am quite happy with it. I've heard it's easy to installl, too, but I had someone else do it, so I can't say if that's true. The bodywork has cutouts for the tail light and headlights. Works great.
