125 to 180 conversion

Am I right in thinking that if I bought a 125 (because it's cheap) but wanted the power of the 180 would I just need to change:

Cylinder kit
Variator..(any washers)
Belt
Gears

And I would need to get a receipt to send off to change cylinder size (I know there has been a thread on this) but doing it myself, I'd still need a receipt right?

 

125 to180 cc

I have found that going up on the cc say 125 to 172-180 on the log book they (that is the D.V.L.A) are only interested if you go down on the cc this is due to the taxation class (the higher the cc the more you pay) so you should be fine IE no enginers reports or comfirmation should not be needed

 

if your goin up in cc dont think you need any proof only reason for proof for going down is the taxation class also i belive you may have to have the cases modded to take a 180 cylinder if there 125 cases

 

lol beat me to it ^^^^^^^^^^

 

Thanks for the quick replies :beer:

That whole registration thing is good then, modding the cases ...really want a 2t 180 dd in project form but none come around, see alot of 125s though

 

125 to180 cc

Year had to laugh at that ,both posted at 10.38 must of beat you on my reaction time (to much drag racing)

 

well how come when i sent my logbook off to change from a speedy 100 to 125 i got a letter saying they needed a reciept as proof
and returned my v5

 

Re: 125 to180 cc

lol that made me laugh bothe the same time
speedy when i reged mine from a 50-125 all i done was put the new engine numbers on the logbook and sent it off saying it was now a 125

 

thats what i did but i got this gay letter back so i need a reciept sayin who did the work on my bike :rtfm: :rtfm:

 

it depens some times they do but i think if u sound like a littlie shit then they make u get a shop to prove that its been done propler

 

Did you change the engine though Speedy 172?
Was it to a piaggio engine?
or did you just put a kit on?

New engine means more work and poses different questions.
is the rear wheel still central, is the mounting safe, do all the electrics work?

If it was just a kit they prob wouldn't have needed more info.

But also going from 50 to a 125 you should need proof to show certain things such as 50ccs dont actually need a high and low beam.
125s and over do if i remember right. so you would need headlight unit changing or change the bulbs and positioning.

 

125 cases have more compression as well dont they minor??

 

a mate of mine did mod his own casings actually anddddddddddd



















his bike done 30 :w00t:
