what can you ride on a cbt ?

well when i did my cbt (16) the instructor said that as soon as i turned 17 i can ride a 125 does this mean do my cbt again on a 125 or ride a 125 straight away and just a scooter or any 125 i want ?

 

any 125 you want (as long as it's below 14bhp or somthing) but pretty much all of them are.

 

so something like dt would be ok how quick are like the 125 scooters 2 stroke ones as standard

 

runner 125, sr 125, typh 125 etc... about 70-75 mph (on the clock)
