33bhp... which bike to go for?

[dgk13]

So you've passed your test at 18... you're allowed 33bhp.

At the end of the day the reason i wanted a bigger bike was to go faster. Which is faster?

A, Full power italian 125 smoker (mito for example)
B, Restricted 400cc or there abouts bike (VFR for example)

I know the larger four stroke bike would have far more torque still as there are no limits to it... but then i'm guessing it weighs a lot more too..

I'm not that fussed about ride-a-blilty... just interested whats faster in a straight line and round the twistys...

Thanks for any help.

Thanks

Cause i was recently knocked off my bike.. which has given my the chance to upgrade with compensation etc... just not sure what is the best thing to do, as my friends are on 125's.... but then if i got a restricted bigger bike i could use it again in 2 years time...

I'll say it before somebody else does

I'd go for the restricted bike over the 125cc.

That way when you get used to the power and want to go faster you don't need to buy another bike because from what I understand from the 33bhp guys the restrictors have a habit of 'falling' out when you get used to the bike

Buy a 99 R1 and restrict it to 33bhp then take the restrictors out. Thats what my mate Kenny done.

def go for 4t 400. They are physically small in size so not going to wiegh all that much more.

Also 4t are so much more practical, if you have ever owned a RS125 or Mito yourll know what its like waiting up to 5 mins to warm it up and then first 10 mins taking it easy in the jorney till full tempreture. Yes you have to take a 4t 400cc slow for first few mins but nothing compared to 2t 125cc.

Also, 125cc highly tuned 2t tend to blow up and top-end along cost me £600 to get fixed, unless your able to rebuild it yourself its very expensive. Then you have to run it in again which is like riding a moped if you keep to rev limits

The 2t 125cc like mito and RS125 as great handling bike and fun but if your sole mode of transport i wouldnt, 400 will have more power (33, 125 2t are about 26/27bhp) and handle well (though havnt rode one)

Hope this helps

Was thinking of doing that...
Whats the insurance like what you've just passed and hop on an R1?

Cause i can get insured for £360 on a mito TPFT.
I take it even though its only got 33bhp that a bigger bike would cost far more to insure?

If i did get a larger bike and have it resticted i would be looking at the 4-600 class.

Although, i mean an R1 with 33bhp is surely no faster then an R6 with the 33bhp?

They wouldn't do the limiting idea if you could limit a wheelie machine and still have it anywhere near powerful, would they?

Hi

The 125s are not as bad as some people make out. No need to sit there with them idling waiting to warm up (they barely warm up doing this, my RS125 at full temp will cool down if left idling). Using the Makita kits and doing the work yourself it is £200 for a top end rebuild. Probably less than you are looking at for doing the valves on a CBR400.

The 33hp restriction does affect torque. Power is just torque x rpm, so to limit power you either limit revs or torque (or realistcally both). Doesn't affect low down torque really, but then that is not of much use.

However, few people stay restricted, and a full power 125 is not much fun with a pillion. Also the restricted bike will be faster (neither the Mito or the RS are anywhere near 33hp at the back wheel, 28.5 was the best the RS managed in road tests and that was the early version with the larger carb). Although the 33hp restriction is meant to be measured at the crank, I suspect that in reality the kits and peoples claims are done on rear wheel hp.

All the best

I had a Cagiva Mito 125,and after passing my bike test,am at 33bhp on a 99' Suzuki GSXR. Personally, I find the GSXR alot more reliable,easier to ride and manouever and am glad i am not still at 2 stroke. The GSXRs accelaration is also alot better and the bike itself is quicker,

Also, Carole Nash,and other insurers said that restrictors do not matter. If i ride a 600,i pay for 600 insurance etc.

So on paper, or online i should say..

The limited R6... is faster then a full power 125?

The limiting process itself, it is just limiting the flow in carbs, or do they have to change the sprockets too?

A 400 at 33bhp will most definatley be faster and more reliable that a 2t 125.
As your looking for speed though if you get a 33bhp 400 it wont be long before you take the restrictors out.
I say go for the 400 it will give you experience on a bigger bike even tho its restricted and you will find it more rewarding.
Saying that there are a lot of lower powered 500/600cc bikes that suit restrictions and between a 4/5/600cc i would go for a lower powered 6.

As suggested by other people,
If i was to take a speedbump too fast on my restricted 600, and the restrictors just happened to get knocked out..
I know my insurance would then be invalid, but what would they do if they found out it wasn't limited? do i just put them in again if i'm still alive after my crash?

A crash is pretty much the only way anyone will bother to find out if you dont tell em.
If in a crash i suppose you have two choices, try and get em put back in before anyone checks it over or mangle the engine beyond the point of being able to check

i have just passed my test at 17 after havin an rs50 (which i wrote off) and a gpr50 and gone straight on to a cbr400, this is a smart bit of kit, unfortunatly my restritors have 'fallen' out, but i have all the relevent forms and certificates so they never really need to find out unless i get clocked at flat out.
giving credit to 125s they are pretty nippy but you do have to buy loads of 2stroke oil and my rs ate its way through spark plugs as you have to revv 2strokes high to get the best and fastest out of them as they have very little down low power.
but id go with a "restricted" four stroke all the way

[Chiz]

I kept my NSR for a couple of months after i passed my test, i only bought my new 'restricted' CBR400 because i got a good deal on it. The NSR was fast enough at the time, now i want a 2 stroke again...

Time for an RGV250.

4 strokes' power delivery is a bit dull, and, easy.

[stevo as b4]

Make sure you don't restrict the RGV to 33bhp! If you do it will run very badly, and will probably end up being less reliable than a normal std one, which is terrible to start with!

[jay_666]

I've pretty much decided that i'm going to go for a Thundercat. It will be restriced for 1 year minimum because of my lack of experience.
