The jerkiness afflicts cars with dual-mass flywheels.
You've got to contend with clutch take-up, as well as both sections of the flywheel moving, before they lock-up.
We offer a lightweight single-mass flywheel, it weighs 7,2 kilos, and besides making the engine rev up more cleanly, it removes the characteristic "judder" or "jerkiness".
The only other option is just to get used to the stock set-up.
