Oh. I know MT has ABS option and I thought there was a throttle restrictor on UK models. Or is use of the restrictor based on type of motorcycle license? I'm not educated on restrictions for different regions so I could be off base here. I do know ABS isn't a option in the US. I do hope it gets adopted soon though. I've never owned a bike with ABS but added safety would be welcome here I do believe.
In Europe you have two versions.
A full power version, and a 45hp version for the A2 license, and ABS or non-ABS of the two.
Australia have a LAMS (Learner approved) version that has a slightly smaller displacement engine, restrictors and a little less power than the US/EU full power version, this to fit within the LAMS regulations.
Norway does not sell the Non-ABS version, even the restricted version, all bikes are ABS.
The A2 restriction can be fitted to any bike, and removed just as easy. But, when the bike is registered it is registered as A2 (restricted) or A (full power) and the A2 version is cheaper (less tax) so you can't just remove the restrictors, you have to re-register the bike with full power and pay the missing tax (with a tax break on the age).
In Norway you can't drive a motorcycle without a license, actually you need a license to drive a moped.
At 16 you can get a moped license and drive a 50cc restricted to 45kph (28mph), or a A1 licence that allows you to ride a 125cc.
At 18 you can get a car license, and you automatically get a moped license at that time.
At 18 you can get an A2 license, and can drive any motorcycle restricted to 45hp.
At 24 you can get an A license, and can drive any full power motorcycle. But if you have had an A2 license for 2 years you can get it sooner by doing a 7 hour course.
All classes require a theoretical and practical test with the authorities.
