de-restrict

[greavous]

hello,
i have a suzuki GZ 125 HS and im just wondering how they are restricted and what can be done to remove this. ive read all over the internet 100 different ways that its done but i thought id come and try and get my own answers.
thanks

Your bike is not restricted in any way, it is already making the maximum amount of power it can without loosing durability and reliability. Only the 2 stroke 125 bikes are restricted with the 4 strokes usually making a maximum of 11-14 bhp in single cylinder form so there is nothing can be done to make it any more powerful unless you have a few thousand quid to spend on it.

Hi

As above, although looking around the Marauder does seem to struggle to get any reasonable speed so seems likely they don't manage to make the 11kW that a learner is allowed.

All the best

damn it only reach's 60 mph i was hopeing for atleast 70 from de restricting it

You might be able to get a bit more power out of it but to be honest it would cost a fortune even to get it to 70 mph and a more powerful bike would cost less. Your bike is quite large and heavy for a 125 so will be slower than most, best leave it as it is as modifications will harm the engine and make the bike worthless, if speed is your thing go for one of the 2 stroke 125cc bikes as they are restricted but can only be legally deresticted after passing the test.

ye i was jsut seeing if i could get some more speed out of it or atleast some acceleration as im going on a rally this weekend and since ill have the slowest bike ill be at the front my freind has a 125 2 stroke and all he did was pull a wire out and it went faster

Did you assume that it might be restricted? Or did your joker of a friend tell you that as a sick joke? If he did then shoot the Cnut!

[greavous]

well theres nothing in the air filter, nothing in the exhaust so the only things left are the DSI and the carb. if i cant find anything at all on it to make it faster ill just start buying some performance parts.

Op, if a cruiser is your thing then sell your bike and buy one of these secondhand for the same money or less, the Hyosung is a twin and is at the upper limit of the bhp available for a learner 125 and will top 70 mph and cruise at 60 mph all day, the downside is that the engine is very complex with 8 valves and 4 camshafts which does not lend itself to basic home maintenance. It is also a very large bike for a 125.

And you can make these Chinese cruisers sound cool. Have a listen to my Baimo Renegade with slash-cuts at www.baimo.co.uk

Im confused? Is the OP misinformed and thought his bike is restricted until told otherwise?

Or does he believe that all 125's are restricted and can be made to go faster by removing/modifying a certain part, and despite being told that this is not the case, either doesn't believe the advice he got, or is hoping that he can still find a magic restrictor device within his bike?

Or lastly does he know and accept that the bike is definately not restricted, but wants to tune the engine for more performance than std, anyway?

What i doubt very much is that he has realised that he has brought a bike he didn't want and finds underpowered/inadequate? If this is the case he certainely does'nt seem to want to admit to it on here!

i bought the bike because its comfy and looks good the only reason i want more speed out of it is to help with overtaking and im going on rallys so a bit more speed would be nice
