Hello there all,

Today was the first time I took a pillion on my 125cc scooter and i could feel the difference in the performance.

I am currently looking out for a CBR600FS and I have a restricted license as I am 18 and just wanted to know if the 33BHP 600cc will feel much different to a 125cc scooter for the pillion in terms of sense of acceleration.

I am fully aware that a 33BHP is somewhere between 5-6 seconds for 0-60mph and tops out at about 100mph, I just wanted to know how it would compare for a pillion on a 125cc.

Thanks

The restricted bike will be fairly dreadful accelleration wise, and would top out at 90-95 maybe.

It would probably be quicker than the scooter, but I wouldnt expect it to shock.

Temeluchus Have you ever ridden a 125 scooter? Do you know how slow they are? Compare it to a restricted 600 and you will be shocked.

Its been a long time since i slung my leg over anything under 750 to be quite honest!

I rode a restricted diversion 600 for a friend, and it was almost coma inducing.

Trust me bikes restricted to 33bhp are slow but 125 i guess its a 4 stroke scooters are a lot worse Laughing

Ive just got myself a 100cc two stroke scooter to get to work on its unbearable Crying or Very sad

125 speed is 125 speed irrespective of category of bike. The speed's will be reached quicker with a bigger bike but they top out averagely similar in this case

Lets do some maths rather than anecdotal crap.

125 scoot say 125kg wet weight. bout 0.11 brake horsepower per kilo

CBR600FS wet weight 185, restricted approx 0.17 bhp/kg

Restricted is a slight improvement-youd struggle to get away from me on my old MZ 250 however. (0.18 bhp/kg)

https://www.eltip.de/MZ%20ETZ%20250%20-%201.jpg

(However if you have the cahones to ditch the restrictors like a real man, will knock your socks off!CBR600FS wet, full power, approx 0.59 bhp/kg-nippy.)

Short answer...Yes
And it will depend alot on how you ride as to whether your pillion will notice.

You can quote figures but untill you have done it you will not know.


I went from a Yamaha RXS 100 to a Restricted 600 and the difference was mind blowing. It may feel slow as shit now if I was to restrict it again but then it was awesome.

It was absolutly fine to take pillions with. Bear in mind, you will be more concerned with not killing your pillion than going flat out.


If you are going to do the math do it properly,

It would more be

275kg @ 14.5bhp
and
335kg @ 33bhp

Allowing 150kg for rider and pillion

This is 0.053bhp per kg versus 0.099bhp which is nearly double for the 33bhp machine.

But this is relitively useless considering it would be more to do with torque than bhp for pulling load.

He's asking what it'll feel like and your saying anecdotal evidence is rubbish, and then quoting bullshit figures. I know which I'd rather trust.

Anyway if you add 90 odd kils ofr a rider in gear then the figures are 200 kils and 12 brake, so 0.06 brake per kilo
the CBR would be 270 0.12 brake per kilo.

IMO this is still completely useless information, but at least its accurate.

A 600cc (even restricted) will be much more comfortable to carry pillions on, even the size of the bike makes a huge difference.

I used to take my kids pillion on my 125, and it handled like crap with them on the back, feeling far too top heavy and unstable.

On my 500 it's a world of difference, I can hardly feel them there. The bike is more than capable of handling with the added weight.
My kids are 13 and 14 so not small children but I've yet to take an adult passenger.

You're saying that a 125cc scooter has the same top end speed as a 33bhp 600cc? Confused

How are they innaccurate? please prove your figures mathematically in response.

My figures are calculated from manufacturers figures.....

CBR600FS is 168kg dry. Fuel Capactiy is 18 litres. 18 litres of petrol weighs about 12.5kg (0.7 kg per litre of petrol.) Add air in the tyres and a few litres of oil the bike will be around the 180kg mark.

So 33bhp/180kg=is 0.17-0.18 bhp/kg.

About the same as an MZ ETZ250.

It WILL be faster than a 125 scoot, but not a massive change.

If it is on stock gearing, that is far too tall for a restricted motor as it is geared to work with a free revving 100hp plus motor. Go get a FX650 and gear it for 160mph and see how well it does.

The problem with the restrictors is you are forcing a high revving engine that needs masses of revs to make decent torque and power then strangling it....

Tis what it says.

I was told a Bandit or R6 restricted would reach 110.

Mine does 90 according to an accurate GP unit, yes there's 20mph in that but there's also a good 1.5K price tag in upgrading too. I'd rather stay on a 'derestricted' 125 that's a bit lacking than get a 600 that wouldn't be much better off for 1.5K.

A 125cc Scootay St3v3, not a 2-stroke sports kicking out 29bhp at 130kg.
While my 600 restricted is no rocket, it can still accelerate quite quickly to 95mph, and that's with my lardy 100kg arse. I've lost a bit of weight now, and the missus weighs roughly 60-65kg so if I were to take her pillion I reckons IF it was doing 0-60 in 6 or so seconds, it would still be able to manage it in 7-8 no problemo, topping out at around 85mph, which is plenty if I'm not wanting to make her cry.

TBH you're not really looking to overdo it when carrying a pillion, unless you've got a small peen and are overcompensating.

If you get a Piaggio Typhoon 125, it will sit traveling the same speeds as an RS125, overall.

Surely? they are both 125cc..

Read my post, it shows using your maths, but taking more into account.

Have you ever got off a 125 then been on a restricted 6, the difference is massive.

My figures show nearly a double in BHP per KG with a pillon.



Just for comparasion,

GSXR600 - 196kg kerb weight + 109bhp

GSXR1300 - 260kg Kerb + 170bhp

+150kg rider and pillion

This leads to 0.31 bhp per KG for the 600 and 0.41 for the busa.



Now do you really think a busa would be only a 1/4 quicker than 600 with a pillion?

No, it is all to do with torque.

Now bear that in mind. Considering the restricted 600 has double the bhp per kg than the scooter by your logic then the difference between a resticted 600 and a 125 is twice that of a gsxr6 compared to busa.



It's not saying this is correct I'm mearly pointing out you are wrong.

When they have the same capacity engine, and don't weight much different I don't see why not?

Oops, missed your first post Chris, said pretty much the same. Anyway Temeluchus, I'm not gonna bother arguing with someone that thinks doing maths is better than 'anecdotal crap' when talking about how a bike feels to ride, which is shit then goes and works out the bhp per ton without taking into account the riders weight Rolling Eyes

Considering this time last month you were doing 'everything within your means' to buy another members R6. Rolling Eyes

You keep reassuring yourself that your 125 is a good a bike as a 33bhp R6 then....
