2024 Suzuki GSX-8R Review – First Ride
Tue, 14 May 2024A middleweight sporty-bike without the backache Photos: Kevin Wing As I write this, in the year 2024, it’s dawned on me that there’s a whole generation of adults that have little to no memory of September 11, 2001. Some weren’t even alive yet, and those who were were too young to remember. One of, if not the, defining moment for my generation is just a page in a history book for today’s young adults, just as December 7, 1941 was for me.
2024 Suzuki GSX-S1000GX+ Review – First Ride
Fri, 22 Dec 2023A tech-laden, long-legged addition to the K5 family Photography by: Ula Serra, Amylee Photography Suzuki has produced more than 180,000 of its K5 999 cc Inline Four cylinder engine in the last 18 years, and now we’re seeing that engine tasked with powering a tall sport touring bike that Suzuki calls the “supreme sport crossover," sitting between the sport-touring GSX-S1000GT that the GX is heavily based on, and adventure tourers like that of Suzuki’s V-Strom line. Leggy sport tourers, or crossovers, aren’t exactly a new thing, and since bikes like the Kawasaki Versys, Yamaha Tracer 9 GT, and BMW S 1000 XR exist, there is already some healthy competition for Hamamatsu to contend with. Suzuki tells us this is its most technologically advanced motorcycle yet, making the GSX-S1000GX a sort of flagship product for the brand.
2023 Suzuki GSX-8S Review - First Ride
Wed, 19 Apr 2023Suzuki fires on both cylinders with its new naked The Route Napoleon is considered one of the best drives across France. It starts near the French Riviera and runs up to the southern tip of the Alps. The route earns its namesake by following the path that the one-time French emperor used to covertly make his way north after escaping his first exile.
2023 Suzuki V-Strom 800DE - Video Review
Fri, 24 Mar 2023Nobody reads anymore anyway The Dunlop tires worked well on pavement and hard packed trails, but in the looser terrain, a knobby tire would’ve been a better option. Videos by Suzuki, Edited by Ray Gauger You’ve read the review (maybe), now watch the video! Skirting through beautiful twisty bits of tarmac intertwined with rocky fire roads, the Suzuki V-Strom 800DE’s excellent new Parallel Twin engine is a peach. On road, the Twin powers out of corners with all of the punch expected of a 776cc 270-degree crank-driven Twin.
2023 Suzuki V-Strom 800DE Review - First Ride
Thu, 02 Mar 2023Suzuki hits a sweet spot in the middleweight adventure scene Flying over the second largest island in the Mediterranean gives a view of rocky coastlines, lush greenery, small villages, and surprisingly stout topography with mountains stretching more than 6,000 ft. into the sky. Idyllic yet rugged, the isle of Sardinia boasts addictively serpentine asphalt and endlessly challenging off-road terrain.
2023 Suzuki V-Strom 800DE/V-Strom 800DE Adventure First Look
Tue, 08 Nov 2022No longer with a V-Twin, but the Strom heritage is still strong The Suzuki V-Strom line is a storied one that most riders are quite familiar with, but today in Milan, Suzuki opened the next chapter: the 2023 Suzuki V-Strom 800DE. While the entire bike is worthy of attention, the showstopper for the new Storms is the 766cc parallel-Twin engine. The V-Twin that gives the Strom part of its name has been assigned to the history books.
2023 Suzuki GSX-8S First Look
Tue, 08 Nov 2022Suzuki's all-new platform is a sign of things to come. At long last, the spiritual successor to Suzuki’s wildly popular SV650 (but not the actual successor, the SV is still staying in the Suzuki lineup) is finally here. Say hello to the GSX-8S, a motorcycle Suzuki says was “engineered from the ground up as an innovative path for future Suzuki sportbikes…” While we all process what that means for Suzuki’s future, let’s delve into the present day and take a closer look at Suzuki’s new middleweight naked bike.
Showdown: Kawasaki Ninja 1000 SX Vs Suzuki GSX-S1000GT+
Fri, 04 Nov 2022A clash between two sport-touring heavyweights Credit: Photos by Evans Brasfield It seems like all the splash lately has been about the ADV category and all the wonderful things they can do and destinations they can reach. We’re not going to deny adventure bikes their time in the sun, either. They’re definitely fun and capable bikes worthy of all the bandwagoning.
