This section is dedicated to offer you, my reader, some comments about the differences between DaytonaRS and 1100Sport.
 

Table of differences

Engine:
 

The main (and almost the only!) difference between the two is, obviously, the engine: the evergreen 2 valves with rods and rockers with a displacement of 1064cc against the "new" 992cc 4 valves engine, that has abandoned the historical single camshaft with pushrod tyming system in favour of a single overhead cam technology, granting for higher reliability at high revving.

The two, apart from the bare numbers which might make them look similar, are incredibly different when on the road, a thing that might seem hard to believe at first!

(here we will talk about "custom engines", thus about engines with exhaust crossover and new eprom; the deductions apply to the stock ones to, but many irregularities and flat spots should be reported for them)

The old Sporti engine is a wonderful engine: it pulls like the proverbial freight train from 2000 rpm (with the right eprom!) and continuosly up to the rev limiter, without a sudden increment of the power or torque.
It just goes and goes and goes till the limiter cuts: the power erogation might look somewhat strange, because without feeling the kick in the back of sudden increase in torque/power phisiological in other engines (4 cilinders first) one might think that the engine is, at best, very weak.
But when checking performances, one discovers that the engine is a bull working very very hal working very very hard, giving you high speeds in a matter of seconds, and pulling so hard even the rev limit in 5th gear is easily reached...

When you come out of a corner along with other bikes, you'll discover how much the engine pulls by noticing the other bikes only in your mirrors!
 

The Daytona instead, has a completely different engine.
It sounds very strange, considering that they share many pieces and that, in fact, the Daytona engine is strictly derived from the one of the Sporti, but, believe me, the two have completely differen souls and tempers.

When you talk about the Daytona, forget the Sporti: the engine is really weak at low rpms, especially compared to its bigger brother.

From 2000 to 4500, the engine is just there, working but in lazy and relaxed way.

Then, between 4500 and 6000 the noise changes, but still it is not going to offer you a strong pull or feelings; as before, it just goes, faster than at lower rpms, but still it is weaker and weaker than the Sporti engine.

Then, a sudden miracle happens: as soon as you go past 6000 its voice changes again, it revs faster and shows some sort of interior rage, starts to pull you strongly and as soon as you arrive to 7000 you discover truly emotional nirvana:
it howls and roars and the rpms fly to 8000 where more and more power is available for your pleasure, bringing you in a new dimension of sound and emotions.

It p and emotions.

It pulls very hard up to 8600-8800 where it starts to lose power and torque, being at last in oxygen debt at 9000 when the rev limiter comes in aid.

You should not get a bad idea of the Daytona's engine: it is a strong one even at lower rpms.
It's a V-Twin after all, but its simply is outdone by the Sporti engine, that at lower rpms is lightyears far from the Daytona's.

But as soon as you make it play high, you'll discover a new world even compared to the Sporti: it is not 10 times more effective than the brother (actually, it has only some 12Hp more), but the power is delivered in such a brutal way between 7000 and 8600 that you always want to go that high to dream.
And, believe me, it makes you dream when it roars past 8000...
 
 

After having shown you the differences about their temper, it's time to be sincere about their performances when on the road.

The Sporti wins when the two are compared on curvy roads, when, in a word, you are racing or just going very fast on a track on (too bad...) open roads in the hills/mountains.

It's incredible and constant torque pulls the bike out of any curve in a glance, taking advantage from the "high flying" Daytona, which actually reaches the Sporti only after some straight.

Thus, the 4Valves is able to catch the 2Valves only after a long straight when coming out of a curve, because it needs much more time to enter in its useful pow enter in its useful powerband whereas the Sporti is already there and flees away for a while.
 

The Sporti, in a word, is more effective when the road is curvy and twisty, but not only there.

A friend of mine who held a Sporti and now holds a Daytona told that, while with the Sporti to pass a track or a car you just needed to open the throttle, with the Daytona you usually need to downshift once or even twice, have the engine roar high and have you disappear past the truck/car.

The Sporti is more usable and easier, more available in a word: you want to play, just open the throttle.
The RS instead, wants more attention, more working from you, but pays back with strong emotions when the engine is singing high enough to let you hear its spectacular simphony.

If you give the Daytona the ooportunity of playing in its ground, between 6500 and 9000, than there wouldn't be any comparison, the Daytona is much more funnier to ride, and that is all.
It is not much more effective, but the fun brought to you by the burtal engine is enough to make you forget about "emptiness" of the lower revving.

Give her what she wants, and heaven is at your finger; constrain her far from her home, and you'll get disappointed.
 
 

To come to an end, they are quite different bikes.
It is hard to believe (they look almost identical), but they have completely different souls, and it is up to you to decide which one suits you best.

I haven't owned a Sporti, neither have I tried one; thus I can speak only about Daytona when it comes to personal comments:

DaytonaRS is wonderful, it can be lazy in a very human way when the throttle is closed and rpms are low, and then turn into a beautiful toy when  the engine is revving high, and the higher it revs, the funnier it gets!

The Sporti (which is much more diffused then the Daytona) has a completely different temper:
you ask, you get, doesn't matter which gear you have in, or how much high or low the engine is revving.
But, and that is confirmed by all the Sporti owners I know, it is less brutal than the Daytona at high rpms: it lacks rage when revving high, even if it grants you tons of torque which brings the aim of rev limiter in any gear easy for everyone.

Now, it is up to you: if you wanna play tough, just take the unique DaytonaRS; if you are more faithful to Guzzi tradition and prefer a "strong everywhere but without peaks" power delivery, than go for the Sporti.

In any case, you won't be disappointed!
