As environmental regulations around the world become more stringent, many car manufacturers have abandoned the original 600c .c engines and replaced them with engine types with larger exhaust volumes, which has also caused the WorldSSP to be more and more scarce in this mid-weight event, in the 2022 season, WorldSSP has greatly relaxed the exhaust volume limits of participating vehicles, allowing six new models to participate in the competition.

List of eligible vehicles for the 2022 WorldSSP and speed limits
Six new cars in the fight! Panigale V2 and ST765R became the new highlights of the season
After the relaxation of the standard, many new cars, including the Ducati Panigale V2, TRIUMPH ST765R, MV Agusta F3 800 and many other new cars have been allowed to participate in the WorldSSP race in the 2022 season, of which Ducati can be the biggest beneficiary of this relaxation of the standard, the 955c .c. V-twin engine used by the Panigale V2, which can be far superior to other competitors in terms of exhaust capacity alone, becoming the only existence in this class.

Another eye-catching new competitor is the Dynavolt ST765R, which was exposed in 2021 and competed in BSB events, ST is obviously an abbreviation from the Street Triple model, which means that this car is not a Version of the Trimph Daytona but a fairing using the Street Triple, if the ST765R can be successful on the WorldSSP field, It is believed to deepen Triumph's willingness to continue to launch the Daytona or other three-cylinder imitation racing models.

KTM RC 8C is still absent, GSX-R750, Superveloce unexpectedly appeared! There are also several interesting models in the list of participating vehicles, such as the MV Agusta F3 Superveloce Retro Imitation, which is also certified as a derivative of the F3 800, but it is very doubtful whether any team will use this noble Cafe Racer style car to compete.
Interestingly, KTM's RC 8C did not appear in the list of 2022 WorldSSP models, which shows that KTM seems to be ready to focus on the MotoGP in a short period of time, but it is really regrettable that the RC 8C, a two-cylinder imitation with unlimited potential, does not participate in worldSSP events.

In addition, thanks to the relaxation of displacement restrictions, SUZUKI GSX-R750 also appears in the list of qualified cars, but this living fossil-level old imitation is currently only a few markets still on sale, foreign media speculate that the addition of GSX-R750 is for the relaxation of the US race, and the chance of seeing GSX-R750 permanent participation in the WorldSSP field in the future is not large.

The glory of the four-cylinder 600 fades, and the R6 and 600RR will eventually be eliminated by the field and the market. After the relaxation of the WorldSSP rules in 2022, it is really a sunny thunderbolt for the supporters of yamaha and HONDA, two traditional four-cylinder 600c .c. imitations, while KAWASAKI has both ZX-6R and ZX-6R 636 versions participating.
At present, the biggest impact should be YAMAHA and HONDA, these two car manufacturers adhere to the 600c.c. four-cylinder engine setting, although YAMAHA launched a larger exhaust YZF-R7 in 2021, but the power performance is far from competing with the Panigale V2, ST765R and other opponents.
It remains to be seen whether the worldSSP king of the past, YZF-R6, can maintain its advantage
HONDA's new CBR600RR is only available for sale in a few markets
KAWASAKI 2022 season will have two versions, the ZX-6R 600 and 636
Yamaha's only hope is to launch the YZF-R9 in the future to follow the trend, but the embarrassment is that the MT-09's current 890c .c.
