Looks decent

With 47 Bhp power, they should have rather named it RS447.

159 kg dry weight.

full LED front headlight features the signature lighting style of the latest Aprilia generation, complete with integrated turn signals. The instrumentation uses an effective 5-inch TFT colour instrument while the handlebar controls are backlit.

The motorcycle looks absolutely stunning! Trust the Italians to come up with a job like this... The Italian Job lol!

I can't wait for a similarly specced Tuareg now. This is what the 490 from KTM was after. Game on!

Finally, they unveiled it after everyone slept off

Luckily, though they botched up the unveiling, they have made a stunning looking bike with some really good specifications. They even claim the highest power-to-weight ratio in the A2 class!

I love this white shade, makes the RS457 look meaner.

The Aprilia RS GP bike-inspired scheme looks good too.

This seems to be the final production version, with a usable pillion seat, rear number-plate holder, mirrors, etc.

Will a R or Factory non-A2 version come later? This seems to go against the CBR500R with the similar power figures.

Looking forward to the BharatGP India launch (read somewhere India prices will be revealed there)

Happy riding,

re: All-new Aprilia RS 457, now launched at 4.1 lakh

Few things that instantly come to my mind.

It produces much less HP being such a big engine with two cylinders. Hence service intervals should be long as maybe compression ratio is low. Any more clarity on brakes? As in what kind of master cylinder etc?
However this would also mean, this engine can produce much more HP if tweaked ( I am thinking about 60hp). Then stripped down to basics with a proper free flow exhaust should be a hoot to ride at the track.

And more importantly what about service? Aprilia service is few and far between in India. I hope they clear these at the time of India launch.

Kawi Ninja400: Dry weight 166kg | 45HP@10500 rpm | 180 deg crank Parallel
Kawi ZX4RR: Dry Weight 188kg | 75 -78HP @14500 rpm | 4 cyl
RS457: Dry weight 159kg | 47 HP @ ?? rpm | 270 deg crank Parallel ?!

Hope they confirm the 270-degree crank. A good reason to live with and to put up with a Brand that can often throw unreliability tantrums.

And yes, a 457 Tuareg sounds like a tasty Unicorn ADV, again, only when they iron out the niggles!

Looks really great! That perimeter frame is unique to this class. Will provide a very strong platform for performance based modifications. Just made the short list of my next bike.

To be fair it really can't be compared to the KTM RC390. The Aprilia sits in a nice week spot between the RC390 and the Ninja 650. If priced right it could be a great option.

I hope Aprilia launches it soon

Ninja 400 weighs 173kg kerb.
Kawasaki zx4RR weight you have mentioned is not dry, its kerb- that means all fluids along with full tank of fuel
RS457 is 178 kgs kerb.

re: All-new Aprilia RS 457, now launched at 4.1 lakh

"I took the eargasmic Aprilia RS660 to the track, only to see it broke down on the outing lap" a quote from one of the US reviewers on YouTube.

The scaled-down version of the RS looks like a wholesome package. The power, weight, and the 270 crank seem like a package that one can resist (especially for people who are looking to upgrade from 150-200 cc).

And the way the Italians packed this thing is close to what you can call the 'Art,' aesthetically speaking.

As they say, looks can be deceiving! Will it be true in this context? Can one trust this beauty in terms of long-term reliability?

Can it stand against the superior reliability standards set by the Japanese? If not the Japs, at least the Austrian's standards?

re: All-new Aprilia RS 457, now launched at 4.1 lakh

Aprilia literally took the A2 license handbook and maxed out everything. It is impossible for any bike to have a better power output and power to weight ratio in the A2 class of motorcycles than this one because they literally maxed it out. 47bhp (35kW) and 175 kg gives it 0.2kW/kg. Thats the maximum allowed number on an A2 license. The only way to get better than this is to lose weight from the rider's own body .

Another way to get more performance out of it is to concentrate on aerodynamics. But that works only with the top-end and there is only so much top end you could offer with the power output capped at 47bhp.

There will eventually be piggybank ECUs available in the aftermarket that could potentially up the power output but this is it. Stock Sub 500cc bikes "Made in India for the World" are not getting any faster than this one. If you get one of these, you are definitely not getting anything made in India that is faster than this for a long time.

re: All-new Aprilia RS 457, now launched at 4.1 lakh

While an excellent product given its frame, engine and the potential is concerned, it is not likely to make a big impact in India, if at all it launches.

Firstly, making it twin cylinder at such cubic capacity is wastage itself. It will be expensive, non frugal, less serviceable at places, and towards the end, the performance will also be so-so. If you have to make a twin cylinder in India, it makes sense to make it around 600-800cc, so that you at least get big bhp for the price.

Not many are in market for a product that's a slightly better Ninja 400, you can't disagree.

Second thing is the 270* crank. While a great thing for torque in general and avoiding need for counter-balancers, it sound so boring.

Moving the firing strokes closer to each other is a way to make your engine a single-cylinder like sounding machine. Not a bright idea for the typical Indian biker as such. A 360 firing is often a better choice for the sound, but top end performance too.

And in India, sound is of utmost importance to most customers- rev and the multicylinder music must play, for the big cash paid.

Sad, but this is how most Indians see their high speed bikes.

Now think again why the KTM twin cylinder bikes are shelved.

You want a hint? Well, we recently got a 399cc for a bit more cash than a 373cc, still a single. No huge mechanic training programmes and no many many GB's of training videos to be recorded.. and not much risk.

You got the point, right?

Years later, we might see Duke 690 make a comeback. As a single. And it makes brutal amounts of business sense.

With my experience at BIC on a KTM trackday with Duke 390s and RC390s against each other, I kinda felt that even above 60-70 kmph, the aerodynamic benefits of RC start to outweigh its weight disadvantage against the Duke.

Which means, anywhere from 70-170 kmph, in most situations, the RC is likely to be in advantage compared to a basic (comparable) naked bike. In fact, RC390 does 179 kmph on console if I'm not wrong, while Duke does 172, although its a crude, unscientific way to conclude this.

So, aerodynamics matter a lot, even at seemingly low speeds.

But yes, I totally agree about the performance.

No doubt, with a twin, there's a huge modding potential to be unlocked from these piggyback ECU's and exhausts and air filters and all.

I think you are talking about inline/parallel twin engines with 180 degrees firing order. Ex: Ninja 300,650

From what I’ve understood so far, 270 degrees firing order is the sweetest sounding inline twin cylinder engine configuration. Ex: INT/GT 650, R3

Not only for India, that will be an excellent global bike too.

It shouldn't be too hard to meet the benchmark of the segment, the KTM ADV390 as well.

The only thing to be seen over time is the quality & reliability of these machines.
