A Fond Farewell from California Speed-Sports

For more than 35 incredible years, Kregg Williams, California Speed-Sports, and our dedicated team have had the privilege of serving the Northern California market—offering some of the most exotic and exciting motorcycles, ATVs, Side-by-Sides, and three-wheelers around. Our passion for powersports, motorcycles, and—most importantly—the people and experiences that come with them, has brought us immeasurable joy every single day. So it is with a mix of sadness and excitement that we announce our family’s retirement from the industry. While we will miss the day-to-day operations and the relationships we’ve built, we are thrilled to begin our next chapter—riding motorcycles for fun and pursuing some new adventures.

This decision, while bittersweet, comes at a time that feels right for us. Ongoing economic challenges, political uncertainty, a general decline in the motorcycle market, looming tariff concerns, a pending lease renewal and increased pressures from some less-than-ideal decisions from our manufacturers—along with our long-held goal of retiring at 60- made this an easy and timely choice.

Kregg founded California Speed-Sports at the young age of 23. Over the years, we’ve proudly represented an incredible range of brands, including: Ducati, Triumph, Aprilia, Moto Guzzi, MV Agusta, Piaggio, Vespa, Polaris, Can-Am, TM, Italjet, Malaguti, Genuine, Kymco, Motus, and GEM Cars. We were also honored to serve as the exclusive U.S. distributor for Arrow Exhaust for many years. In 2020, California Speed-Sports relocated from Livermore to the famous Arlen Ness Motorcycles facility in Dublin, which houses one of the most beautiful showrooms in the U.S.

Kregg’s love for motorsports began early, riding and racing District 36 enduros and hare scrambles with his father as a father-son team starting at age 6. That passion continued into road racing, where Kregg spent 8 years competing in the AFM aboard his Aprilia RS250. He later raced in the Aprilia World Challenge Cup Series and earned his professional car racing license, competing in the Formula Mazda Series for 5 years across the U.S.—and even tackled the legendary SCORE Baja 250.

What’s Next for California Speed-Sports?

Our regular business operations will officially conclude on October 31st. In the meantime, we are wrapping up existing commitments, including special orders, warranty work, service jobs, and selling our remaining inventory. Come take advantage of amazing deals! We're clearing out everything in the store — don't miss your chance to save big on: clothing, accessories, fixtures, memorabilia, wheel chocks and many many more items.

If you're in the area on Saturday Oct 25th stop on by for one last gathering of friends and fellow riders.

We are pleased to share that our Service Department operations will continue under the capable hands of our longtime friends, Tim and Susie of Pro-Cycles, located just upstairs from our current service bays. Along with Tyler, our existing factory-trained technician, they will continue servicing Ducati, Triumph, and Aprilia motorcycles. Please note that warranty work will no longer be available. For future service needs, you can reach Pro-Cycles at 925-574-5410 or visit them at www.procyclesca.com.

From the entire California Speed-Sports family—thank you. Thank you for the memories, the stories, the laughter, and the lifelong friendships. It’s been an amazing ride, and we are honored to have been part of your journey.

Now, it’s time for us to hit the road and enjoy the ride ourselves. We look forward to seeing you out there—in the twisties, at the track, or somewhere off the beaten path.

Arrivederci,

Kregg & the Entire California Speed-Sports Team

This increase will guarantee a better torque curve with an increased peak value of 125 Nm and a confirmation of 217 hp with Euro5 homologation. New engine shaft to increase stroke to 53,32mm and new top side engine basement.

Since its first launch, the RSV4 has been worldwide appreciate for its perfect chassis balance that gives on track the perfect feedback of a solid front end, precision and nimble cornering.

The latest demonstrations of this unwavering commitment to excellence is the new RSV4, a bike boasting refined mechanics and aesthetics, with revisited electronics and ergonomics. Designed to put the super into Superbike, it emboies the power and brilliance of the Aprilia dream like never before.

In light of KTM's recent financial troubles many of you have been asking over the past couple of months what will happen to MV Agusta. Well today MV Agusta confirms that Art of Mobility S.A., a company controlled by the Sardarov family, will regain full control of the MV Agusta Group, officially marking its separation from KTM.

After a successful year for MV Agusta, the financial situation recently unfolded at PIERER Mobility AG could have significantly impacted the Schiranna brand’s operations. This strategic agreement ensures that MV Agusta remains completely uninvolved in KTM’s ongoing financial restructuring process, allowing the company to continue its positive growth path. Over the past 18 months, MV Agusta has strengthened its financial stability under a fully revitalized management team. This is expected to be completed by end of July.

What practically changes in the daily business? Nothing, we are and will be doing business as usual. Speed-Sports and KTM's North America Office, Team, Product, Parts, distributions, and Brand are here to stay and maintain the same quality level we built also thanks to KTM support in this past 2 years.

The new Investor company is committed and ready to enable MV Agusta and our Operations in North America Office to keep growing, improve, and develop further business with our partners.

Timur Sardarov – CEO of Art of Mobility S.A.: “This is a moment of pride for all of us at MV Agusta. Regaining full control of the company means we are now stronger and more focused than ever on delivering excellence. Over the past two years, the company has significantly strengthened its processes, systems, and workforce. These structural changes are the foundation of the extraordinary results achieved in 2024 and will continue to drive our success in the years to come. I have full confidence in our leadership team, whose vision, combined with the dedication and professionalism of our renewed dealer network, will take MV Agusta to new heights. My commitment, and that of my family, is to be a vital force for the Varese team, the region, and all our partners.”

The Aprilia Tuareg 660 WINS the Africa ECO races twice in a row!!

The NEW Tuareg Rally Edition is scheduled to ship in May of 2025

The Aprilia Tuareg Racing Team geared up to tackle the most eagerly awaited challenge of the year: the 2025 edition of the Africa Eco Race, which will officially start on 28 December in Monte-Carlo. After their winning début last year, Aprilia Tuareg Racing has set sights on the ambitious goal of defending the 2024 title.

Defending champion, Jacopo Cerutti, will be striving to replicate his successful 2024 performance, where he won in his rookie season, making the Tuareg a reference motorcycle in this legendary rally raid. Riding alongside him will be Francesco Montanari, who already participated in the 2024 edition, demonstrating consistent improvement, as well as new entry, Marco Menichini, a promising young rider making his début astride the Tuareg Rally in the Junior class, which is reserved for competitors under 25 years of age.

Following the start with the classic presentation parade in Monte-Carlo on Saturday, 28 December, bikes and vehicles will set out for the African continent to begin the 12 stages. The 2025 Africa Eco Race will start from Tangier on 31 December and will end on 12 January at the legendary Lac Rose in Dakar. The route for this 16th edition will include a total of 5,903 km, including 3,572 km of timed sections, crossing over the gorgeous landscapes of Morocco, Mauritania, and Senegal.

During 2024, in preparation for the Africa Eco Race, the Aprilia Tuareg, developed in collaboration with the Guareschi brothers’ GCorse, dominated the national and international rally raid scene. Some of the more noteworthy wins include the title in the Motorally G-1000 class, victory in the Hellas Rally Raid M6 class, and triumph in the multi-cylinder class of the Baja Aragón, also with Jacopo Cerutti. These results confirm the competitiveness and exceptional performance of the Tuareg on any type of terrain, ready to leave its mark in the 2025 Africa Eco Race as well, for the second year in a row.
