 Posted: 14:01 - 07 Jun 2016 Post subject: First Bike for Big guy |
 |
|
Hi All
Just wanted some advise from all the experience on the forum.
I have wanted a bike for many years, but due to various responsibilities and what not, I stuck to driving a car. But now, at 31yrs old, it is time to realise this dream.
I am a great fan of starting small, because obviously there is greater forgiveness in throttle and weight, and gives you a bit more space to come into your own before straddling a bigger bike.
However, I am 152kg (335lbs). As much as I want to do the responsible thing and start smaller, I fear a 125 or 250cc may lack the torque I require to realistically learn on, due to my size.
Second problem is due to my size, I have had a few manufacturers say ideally I would need a more sturdy frame and suspension which I wont find on a smaller bike.
Lead me looking at the KTM Duke 390 perhaps? Must admit, I don't like the styling much, but is ok.
Then I heard that a person can restrict a bike, so thought perhaps I could buy a 600cc and restrict it down to a more "Learnable" power?
I really like the superbike look, and was thinking maybe the Kawasaki ZX6R. I am not a speed freak at all, I just love the aggressive styling and fairing as in comparison to the naked bikes or Dakar looking bikes.
Like I say, I am 31yrs old, good career, not a speed freak, and have a profound and healthy respect for power. But more importantly I have no willingness to kiss the tar being a fool.
Fastest way to kiss the tar is to ride outside your skill level, or power readiness, and I don't want to be a statistic. Is the restricting possible, or any advise would be greatly appreciated.
Thanks so much. |

You have two routes:
Do your CBT, get a Honda Varadero 125 / Derbi Terra 125 or similar big 125, tool around for a bit, then do your training and tests (and immediately realise that time on the tiddler was largely wasted).
Or
Do your CBT, then go straight to your 'A' training and tests. You'll be learning on something 600cc+ like an ER-6 or MT-07. After that, I can't see why you'd want to go back down to a 390, when KTM do a 690.
Honestly, at your age and size, I'd skip the tiddler and go straight on to 'A' training. I had fun on a 125 and buy the point about small being forgiving, but things have changed now and you need to spend some time training on a 600+ sooner or later - and it might as well be sooner. ____________________ Biking is 1/20th as dangerous as horse riding.

Aaah, got you. In that case, something like a Duke 390 might be viable, although I'm not convinced by the quality of that platform.
I might look at the Honda CB500F or X as well - it's pretty much a do-anything machine designed for user friendliness.
I'd definitely skip the 125, it is going to struggle a bit. Even a 250 offers substantially more torque. ____________________ Biking is 1/20th as dangerous as horse riding.

@herulach - The restrictor restricts not just throttle, but power and torque. So off the mark power would be lowered as well, not just the top end. It is easy to say "Just don't open the throttle as far", but I'm sure most people in accidents did not intentionally do something wrong like pulling back on the accelerator when the bike jerks them back. But these things can and do happen, and seem silly to a seasoned rider that can put these things into logic and practice now.
I'm just trying to make an informed decision, mitigating as best I can, potential for difficulty in learning, and being as safe as possible.
Could you maybe explain a bit more on the technical side on why an inline 4 wouldn't be for me, and what you advise alternatively?
@Rogerborg - we tend not to get a lot of the engine ranges you guys do.
For instance, we get the 125cc, the new 300cc, 600cc, limited dual purpose 750cc bikes, and 1000cc and over.
We don't get the 400cc or 500cc motor sizes here. If they do exist, they are grey imports and you battle for parts and servicing.
The Honda CB500F you mentioned, for example, doesn't exist here. We start that Honda range at the 750cc, and is quite a jump. |

Capacity is only half the story, it's about how bikes deliver the power. On the inline 4s that I've tried, you have to chase it, which encourages "spirited" riding. Twins and singles deliver lower down, and reward being ridden more sedately.
It looks like you can get the Honda NC750X? It's got a low revving, low powered engine designed to deliver lazy torque. It's not a light beast, but the weight's down low and I doubt you'll have any trouble handling it. It's pretty much the definition of "biggish sensible bike for biggish sensible chap". ____________________ Biking is 1/20th as dangerous as horse riding.

I was being somewhat facetious, however throttles aren't a magic switch that makes you go 0-rocketship in no time. Genuinely you'll be fine starting on a 600.
As to torque, inline 4s deliver less torque but more power at the top end as they (generally) rev harder. Twins/singles are more like driving a diesel car vs. a petrol one. Not necessarily slower for the same power but delivery is a lot different, more low down power, but less top end.
As roger says, engine size isn't everything either. An NC750 is what 55hp, vs. 120 out of a ZX6, even though its a bigger engine. ____________________ YBR 125>FZS600 |

Much appreciated herulach, makes sense.
So to summarise so far:
1. ZX6R power delivery is dependant upon a more high revving rider and probably not a new rider, realistically. Indicative of the inline 4.
2. Restricting the ZX6R would just make learning with it more difficult as the power delivery wouldn't be there as readily as it needs to be.
3. Twins and Singles deliver more low down power without needing to rev as high, and more often than not, come in bikes with a more comfortable riding position.
@Pjay - We only get the 1200 Tenere here. Bit much for now, and must be honest I don't like the styling. Very popular bikes here are the BMW GS range. Yes, we are debatably urbanised, dependant on where you are, ha ha ha. Its more the "High danger areas" you need to watch out for than non-tarred roads. But arguably, no bike will outrun a bullet, so best to steer clear. We have taxis here that take aim at motorcyclers, which has forced a lot of riders to go the dual purpose route and stick to local commuting only, and majority riding done in mountains and trails. Once again though, I just don't like the look of the dual purpose bikes. If I were to want to do offraod, I would buy a specific bike made for it. I just don't see the appeal, personally, to want to try get a 1200 BMW through the sand and along paths. A nice YZ250 2 stroke would do a better job. |

Furry muff. I would love to ride out there on those trails at the weekend. The BMW's are obviously better at the job, but those 750 Teneres were an old fantasy of mine, I'd realistically want something more up to date, but nothing would grab my attention at a mountainside cafe more than an old school Tenere. |

You are focusing too much on the restriction. My understaning is you've read too much horror stories about sport bikes having surge of power.
What you can do is buy at least 600cc bike that has smooth power delivery.
Also bear in mind 152kg means that the bike will need the power. The standard power calculations are done at 80kg rider. In your case you'll need more power not a restriction.
You have said you like sport bikes. ZX6R is a good choice. For example look at the power delivery:
https://motorcycleperformanceanalyzer.com/kawasaki/zx-6-r-2007/
Acceleration of the bike is measured in metres per square second m/s2.
That means how fast the bike accelerate. If you put 152kg at the link above you'll see that the acceleration drops down from say 4 m/s2 when doing 60kmh per 80 kg rider to 3 m/s2 when doing 60kmh per yours 152kg.
Means forget about the restriction. You'll be fine with normal power. Most 600cc will struggle with that. This is the reason why many people buy 1000cc when touring with a rider and a pillion passenger (2x80=160kg).
Get a unrestricted 600cc and my bet is you'll go pretty fast to 1000cc at some point.
You will need to try bikes to see what you like. For example twin engines have more torque and theoretically are better suited for you.Having said that if you like sport bikes you may find them very boring. IL4 engines are the definition of sport bike.
Some people may enjoy exactly the high rev screaming of the IL4s.
You will need to try and find what is that you like in biking. ____________________ Adrian Monk: Unless I'm wrong, which, you know, I'm not...
