The key reason for the Suzuki GSX-S1000R being pulled off the market is due to the emission norms.
Suzuki has officially confirmed that the GSX-R1000 will no longer be sold in the Japanese and European markets. The famous GSX-R1000, adored by many motorcyclists all over the world, can be considered a cultural milestone in the motorcycling industry, comparable to iconic models like the Kawasaki Ninja and Honda Fireblade.
Suzuki's decision to completely cease its racing efforts and the discontinuation of the GSX-R1000 are clear indications that the company intends to focus on other non-performance-oriented initiatives for the time being. However, Suzuki's litre-class supersport will still be offered in its current form in a limited number of markets, including North America and the Philippines, although these markets can also await the bike's discontinuation.
The key reason for the GSX-S1000R being pulled off the market is due to the emission norms. The 999cc inline-four litre engine is incapable of meeting Japan's and some other regions' stringent emission standards. Meanwhile, the Japanese manufacturer is said to be working on the next-gen GSX-S1000R, which will also feature an all-new engine. According to rumours, this engine could borrow a lot of technology from their MotoGP bikes. It's a different story, though, that Suzuki has also pulled out of MotoGP in 2023.
There is a lot of anticipation around the launch of this new engine, nonetheless. If you remember, Suzuki had also discontinued the previous generation Hayabusa, years before the arrival of the new model, so, there is a good chance that the next GSX-S1000R will follow the same strategy.
