despite agreeing that buying a bike is a subjective decision, we are willing to go to great lengths to convince everyone (especially ourselves?) about the objectivity of our decisions :)

You obviously haven't read this thread, as the video you're referrencing and others in this thread have been discussed.

This is in referrence to the video you've linked to. IMHO it isn't more representative as the modifications aren't listed, so there's no telling what was positive/negative, nor any indication of the cost of modifications.

The V4R makes the most power, but even they say that it doesn't really come alive until 12K rpms. It obviously has the race exhuast, a factory tune for the exhaust and aftermarket carbon rims.It also looks to have aftermarket sprockets, so no telling how the gearing affected the dyno results. Far from stock, yet it really didn't make that much more power. As outfitted, it is easily twice the price of any other bike in this 'competition'. Even with the lighter exhaust, wheels etc., it was still a pound heavier than the BMW. As mentioned in the video, there is more power to be made as the current tune is rich. Weight was 423 pounds.

I would rather see the baseline numbers, as that is what the average Joe can expect from the factory. It also isn't dependent on how much one can spend to extract more performance. Stock versus modded, although as I said before, no idea what modifications were made and what they cost.

V4R Stock 183.81hp 437 lbs Modded 199.86hp 423 lbs

The v4r 'mods' here comprise the 'race kit' which is the standard factory upgrade available to Joe Public!
Appreciate there are handling mods with the carbon wheels but they won't influence the power figures, the sprockets may be different but the gearing is still OEM.
So the power run in the 650ib video I shared is representative. :)

The gearing for the V4R is 15/42 and the V4 and V4S is 16/41

Having the Ti conrods is probably better than the "M" lightened valve train tricks for longevity and one huge aspect that hasn't been addressed is the durability of the engines.

The Aprilla loses for that due the the letter in the new issue of Roadracing World Magazine which has evidently exposed the valvetrain durability problem and ECU logging of off-road activity.

The Average Joe can't afford the V4R, let alone the race kit, which is why I said It also isn't dependent on how much one can spend to extract more performance. I didn't see any listing of modifications to the bikes, so no telling what gearing each is using.

The stock versus stock video is more relative to me and why I said The BMW is the lightest, makes more horsepower and is the least expensive bike in the 3-bike comparison. This was before AndreiD noticed the BMW pull was done in 4th gear. Upon closer inspection of the video (the 3-bike comparison where they're stock), I noticed that both the Aprilia and BMW pulls were in 4th gear, and the Ducati pull was in 5th gear. Whether that was done to do a pull in the closest 1:1 ratio or just a mistake I don't know.

The competitive motorcycle models available to consumers is a win for all of us. Using the 6-bike comparison data for the Aprilia, BMW and Ducati, my comments on weight, power and cost (pick any two usually works). Bear in mind for cost I'm estimating the cost of the bike and modifications:

The Aprilia is the second most powerful, with an exhaust and tune. Cost is about $29,300, putting it in the middle of the three. Weight is 23/24 pounds more than the Ducati/BMW respectively. Power and cost are the two positive attributes, but both are less than stellar IMHO.

Power - The Aprilia is an 1100 model (1078cc). The BMW and Ducati are 1000 models (999cc and 998cc respectively). The displacement advantage alone should show on the dyno. That the dyno plot is very smooth with good AFRs across the board means there really isn't any more significant power to be made. The BMW and Ducati will both gain power with a tune to smooth the AFRs.

Cost - At close to $30K already, chasing down any additional power will be expensive, and trying to decrease the weight will also be expensive.


The BMW was the third most powerful, with an exhaust. Cost is about $26K, making it the least costly bike of the three. Weight is 1 pound lighter than the Ducati and 24 pounds lighter than the Aprilia. Weight and cost are the positive attributes, being the winner in both of those categories. Of significant note is that the BMW lost horsepower upon installation of an aftermarket exhaust. Slapping an exhaust on a bike without a tune for it is ignorant at best.

Power considerations are that the only two bikes that bested the BMW had:

More displacement in addition to an exhaust and tune (Aprilia).

Equal displacement with an exhaust race kit, lighter engine reciprocating mass (allowing higher rpms) and aftermarket carbon fiber wheels (Ducati).


The Ducati was the most powerful, with an exhaust/tune, aftermarket carbon fiber wheels and possibly gearing. Cost is about $50K+, making it the most costly bike. Weight is 1 pound heavier than the BMW and 23 pounds lighter than the Aprilia. Weight and power are the positive attributes.

The BMW and Ducati had AFRs that weren't ideal. Increased horsepower for both will be gained with a proper tune. .

Oldman,

Do you have amnesia? How many times are you going to try n make the same point in this thread? The horse has been dead already.

I added information that I hadn't posted. Sorry if you didn't see the differences.

^San, I know you wern't arguing in the literal sense, but owning 3 bikes? That's pretty unusual for sure.

Good stuff as nobody else has that insight frankly. Keep it coming!

I have three motorcycles and five 4-wheeled vehicles. Two I bought for my kids, and three are just for me. Mine are a 2016 Tacoma Sport 4X4, a 2007 Exige S and a 2017 GT-R. Pick the right tool for the job.

I have had my new V4R , Race build only since April 24th, Been on the Race Track 5 X now and I love the bike... I just picked up my New BMW S1000RR M package last weekend for Racing only too... I will give my unbiased opinion on what bike I like better on the track only, unfortunately probably won't Race the BMW this season because I still need to get it Race ready per CCS- ASRA rules..I do plan on doing track days on it and also plan on testing both bikes back to back... Stay tuned..
