one for the bikers

Hi all,

I have learnt something new from this thread, although I was aware of the 33bhp limit, I assumed that you had to buy a bike that produced this, and I didn't know that you could ride any bike as long as it was restricted.

How do you actually go about restricting a bike? can any bike be restricted and what do you use?

(sorry to hijack the thread a little)

Cheers
 
You can buy a bike for example mine, its a 125 Dragster that will do 65MPH, i can DE-restrict it to be a 180cc Dragster and have it go about 94MPH. To do this its like a car, you put a induction kit on it, for a moped i would change my exhast, air filter and then find were the restrictor is and get it out, may need a new carb.

Not looked into it to be honest, may do in the future but thats a example.

good lookign 125's race reps
suzuki rgr 125 (looks liek a much bigger bike than a 125)
yamaha TZR 125 rr
honda Nsr
aprilia rs125
cagiva mito 125 (looks like a miniture 916)
however all of these will need high maintenance

hmmm what do you mean high maintenance ? like parts chaning etc ?

Not quite sure you can just magically de-restrict it from 125cc to 180cc :confused:

De-restricting is the term applied to removing restrictions put in place to cap power. You are talking about upgrading things.

Some of the above are highly strung 2 strokes, that if not looked after/warmed up correctly/given right oil will sieze as soon as you look at it.
2 squeaks are fun, but it didnt take me long to get fed up of smelling of 2TX after a long blast.
Now Castrol R, thats a nice smelling 2-T oil :D

I think i'm a bit dumb.
I'm 23, and let's imagine that i want to go out tomorrow and buy a 600 gsxr (without restriction).
Would i be right in thinking (i've had full car license for 5-6 yrs) that i would need to take my CBT, then do a direct access course?. Or would i have to wait a further 2 yrs after the CBT?.

Book your CBT, then DAS this costs about £400 quid this includes tuition, hire of bike, test fee. It's usually 4/5 day course (9-5 job). But, before you do that you need to pass your Motorcycle theory test.

which would be better 2 stroke or 4 stroke am really confused bout this ?

4 strokes are smoother and lazier, but for the same engine size don't make as much peak power.

2 strokes require more effort to ride (well to ride at any speed, anyway) because you need to keep them revving high and in the powerband to get any go out of them.

At this engine size - if you want to pootle get a four stroke, if you want to go quick, get a 2 stroke.
 
high strung race rep 2 strokes will need good quality 2 stroke opil (smells ace too ) they will often need a piston + ring change every 10,000 miles just to kep them running nice and prevent problems,this is quite easy since a 2 stroke engine is a a mechano set tbh, also as with any engine make sure its warmed up properly before thrashing it more so on a 2 stroke as the rev higher meaning more stresses on the engine.
if it was me buying a 125 i would not touch a 4 stroke too slow too lazy and too boring, but then the maintenance side does not bother me as i am pretty competant with spanners.
also with a decent 2 stroke race rep bike like i listed, if you every do you test you can upgrade the power "quite easily" to 33bhp on them anyway since most of them are downtuned hugely to meet the restrictions on learner riders

You can restrict anything, what I would recommend personally, is take your CBT, ride a 125 (14.6bhp or less is the law, not 11.3 or whatever people have said), the 4 stroke 125's will be learner legal standard(most develop about 13bhp), ride the 125 for 6 or so months on L plates, I dont see the point in getting a 2 stroke while you are only on your CBT, because to de-restrict it and get 29bhp from it would be illegal anyway, so get a reliable 4 stroke 125, yes they are a bit slow, but they arent that bad, I loved my CBR125 when i had it for 6 or so months, it would easily go faster than NSL so there isnt any problems of not being able to keep to speed limits. Then you can take the 33bhp test, then get what you can afford, restrict it and away you go, then you can either wait 2 years and pop the restrictors out and be road legal. Or when you turn 21 take accelerated access and take them out that way :)

I am on my 33bhp licence and ride a CBR600, its not cheap to insure but I can afford it so I may as well bite the bullet while I am young.
 
get a cagiva mito, 34bhp when de restricted but no copper will do you for it (12 bhp when restricted)

faster the the RS and will out handle many 600's on the twisties

it is max 33bhp yes, not on engize size. 2 stroke is loads better than 4 stroke, and easier to fix yourself with a little learning.

2 points, well 3 actually, of complete and utter rubbish.

No 125 2 stroke will get 34bhp, not without thousands of pounds spent on them, a de-restricted RS/Mito with race system and a few other gubbins will only develop about 29 at the wheel when under a test.

A copper WILL do you for riding a 125 de restricted on L's, they arent stupid, you can hear they arent restricted when they hit the powerband and they will just see the rate it accelerates and notice the L plates and know its illegal.

The RS is a great handling bike yes, but i dont think it would have a 600 on the bends, you cant put that down to the bike, its all down to the rider and the conditions.

Just my tuppence.

Not true. My CR125 when I had it made 42bhp on the dyno. It was quite highly tuned though but had nothing you couldn't buy from the shops. 34bhp is easy with certain 2 stroke 125's. Even my DT125 was making 29bhp at the fly and it had potential for more.

Well motocrossers dont count, i meant road bikes. :)

Even so, getting it to develop more power while he is on L's is still illegal :)
