Speed Twin 900 Vs. T100 Vs. T120

The brakes on current T120 are more than capable, particularly compared to the older versions. I have an 18 and those brakes are just OK, at best. But, I've ridden the 18 over 13000 miles and have never had an issue with emergency stopping.
I'm certainly not talking down the Speed, it's a great bike. If it was more comfortable, I'd probably have one. But I'd still have a T120 because, for me, it's a better all-around bike.

 

Wire wheels are a bit of a bummer. I have had one flat. I opted to spring for tubeless spoke wheels for my 18. Made a nice difference weight-wise. I've also had a screw in the rear with the tubeless setup. I'm just lucky I guess.
Truth be told though, I don't think the tubes are a huge draw back, just a minor nit-pick.
Some folks go years running tubes with no flats, it's just luck of the draw.

 

Tubes are no more prone to punctures than tubeless, they're just more of a faff to fix. In fact you could argue that a tubed tyre with a 4mm HD tube is slightly less prone. I've had a flat rear on the SS and relied on roadside recovery to get me home. I now have HD tubes front and rear with a dose of that green, puncture filling shite in each for what it's worth. I've fixed a couple of tubeless punctures roadside in the past so I agree that is a bonus but not worth the cost of changing wheels for IMO. Out of desperation, I've ridden the dirt bike home, around 15-20 miles in the past with both front and rear flats on separate occasions but that has wheel clamps to keep the tyre on the rim and certainly not recommended. On a road bike with road rims and twice the weight, forget it.

 

I once had a puncture in a tubed tyre and it deflated so fast it could have had me off. I've had more than my fair share of punctures in tubless tyres but so far they have all been slow punctures and got me home, but I do carry a tubeless repair kit just in case. It is not possible to replace a tube at the side of the road without carrying a shed load of tools. Personally I will never ride a road bike unless it is tubeless.

 

At some point you will need all the braking power the bike can muster because you will mess up, just as everyone who has ever ridden a motorcycle for any length of time has at one time or another. Heavier bikes need more braking power, simple physics but brake feel is just as important. An over-braked machine with fierce initial bite and the ability to easily lock the front wheel with 1 or 2 fingers can be a liability. Bike handling and rider control is a huge subject but, generally speaking, a large heavy bike with "slow" steering will require more input at the handlebars. Once learnt though, even large overweight tourers can be hustled through bends with relatively little effort.

 

No one can tell you which bike you'll be more likely get in a fix on or get in trouble with. Too many unknowns for even the gleaming brilliance of an internet forum to determine.
Honestly, I think you're overthinking things. It's easy to do with all of the information and opinions online.
Motorcycling is a risky hobby. The asphalt is just as unforgiving when riding a 250 as it is a 1200. Yes, the 1200 will get you there faster, but danger lurks regardless of displacement.
Both the ST and T120 will easily handle all but the top couple of percent riders on public roads. The ST is faster, and maybe that's a point against it when considering safety. But much of that boils down to the right wrist of the operator. Comfort, type of use and style should be large part of a decision. Beyond that, either one will be more than capable of getting in trouble and hopefully bailing you out.

 

You really are overthinking it now, at least IMO. Both bikes can get you into trouble, both bikes can get you out of it. Just test them and buy the one that you’re comfortable on and confident in. You really can’t make a mistake with either.

 

Although there are differences between the bikes you mention they are all broadly similar so, IMO, you're no more likely to get into bother on one than the other. Some will say (and have done in this thread) that they are all too big, heavy and powerful for a beginner but I disagree. "The throttle works both ways" is an old and well used cliche but perfectly true. 50 bhp or 200bhp, you ride it accordingly with the required self control. If you don't have any, stick to bicycles. I jumped straight from a lightweight 250cc, 23bhp trail bike to a 300kg, 120bhp super bike with no issues, at least none that were my fault. You just "recalibrate" If I can do it anyone can. The risk from other road users is probably the biggest any cyclist/motorcyclist faces and for a large part at least, beyond your control irrespective of what you're riding.

 

Personally I'd consider the 1200 speed twin because as it's got tubeless tyres you'll be able to have more choice on what to fit (sports touring would be my choice as they perform better in poor conditions and warm up quicker). With it's front twin discs it'll stop better than something with just one and the ABS will prevent thd wheels from locking up.

 

If I may add my two cents or maybe rather wheels:
I was in a kind of similar situation: just made my road bike license and now wanting and looking for my first bike.
I immediately fell in love with the looks of the T120 and I like the gentlemen-attitude that can come with it.
I do not intend to do races, I just want to enjoy.

Therefore to me after reading quite a bit I came to the conclusion that if racing is not a priority the T120 is a very good bike.

In the end I received my driving license, drove from the license department to the dealer immediately after reception, test drove the T120 and ordered it shortly thereafter.

I also heard I should test at least ten bikes before making a decision. But in the end the bike is able to do more than I am right now and will be for quite a time. And for me the search is not the key element, but the joy.
And I felt so much joy riding the T120 that I decided not to blow up a search just to have one done - knowing that theoretically there might be a bike out there that might have felt even better. But not knowing it it doesn't bother me.

Regardless of the experience you have to have respect and decency when riding you bike - probable more of both when being a virgin rider.
I personally think that this is the advantage when starting to ride with older age - we are (or should be) a tad more mature than us as 20-year-olds and therefore should be capable to handle the power with respect.

Anyhow: regardless which bike you choose: you'll be happy with it and enjoy it.

 

Congratulations !
Will you share some pictures ?

 

Wonderful bike ! congrats again

 

Congratulations…..
