The gear change -1 +1 feels great so I don't regret it. No surprises there, power feels more accessible and I will never miss the top end speed. Should top out at ~165 now but I rarely ever get above 100.

Lithium battery saved 3.5 LBS, was a perfect fit and has not let me down yet. Will be interesting to see if it can hold a charge all winter.

 

There was a big surprise when I changed my tire. I was on a set of worn out Q3s in 120/60/17 190/50/17 size. The worn 190/50/17 Q3 weighed 10.3 pounds. It still had a bit of tread on the sides and completely worn down in the center, so if it was more evenly worn would have been even lighter.

I replaced it with a 190/55/17 Q3+ which weighed 14.45 pounds. So that is a difference of 4.15 pounds. About 1 pound of that difference was due to the different profile. 190/50 is the lightest and 190/55 is the heaviest. The rest of the weight loss was due to tread wear.

The front tire 120/60/17 Q3 is still on the bike. Brand new it weighed 8.8 pounds. Probably weighs 7 pounds now and I will be changing it soon with a 120/70/17 Q3+. The new tire weighs 10.1 pounds so I will be gaining another 3 pounds there.

I weighed the tire/rim/sprocket/rotor/spacers so I can easily will keep an eye on the tire weight as I put miles on, to get some idea how tire weight relates to mileage and tread depth. I only put 1500 miles on a year so these tires will be around for a few years unless I get to the track.

So if you are dragging a bike I guess you could grab a set of worn in 120/60/17 190/50/17 and knock 7-8 rotational unsprung pounds of your bike. What would that be worth .5 second off the ET of a stock bike?

For what it is worth, the Q3 and Q3+ have been awesome tires on the street. Great feel and grip even with cool road temps

 

This will cut 8.38 lbs off your bike

 

I have an FMF slip on, but already installed Zbomb and gutted the intakes. Before I install the FMF Id like to get Danos ECU reflash or Zfi+AFM or all three. Maybe next season. I do love the sound of Akrapovic but I got the FMF for $100 couldnt pass up that deal.

The FMF muffler and S pipe weighs 2690g (6 LBS)
Not sure how much the stock muffler/cat weighs will find out soon, ~13.5 LBS from what Ive read

Akrapovič claims what is removed weighs 13.7 lbs. Their slip-on and pipe weighs 5.3 lbs.

 

Less rotational mass is a very good thing.

 

But then he had to add some back with the tire.


OP- "You Is A Injaneer".

 

Better than having the heavier drive system though. Having light weight rims is VERY nice but so expensive.

 

I would love to get the BST set. Not sure if I should get them for this bike or wait until I get a 2017.

According to one seller, BST weighs 9.7 LBS rear (with sprocket carrier, bearings, cush drive, inner race, and “hardware” BUT another ad said the steel bearings add another ~1.1 LBS so 10.8 LBS total
Stock rear = 11.71 rim/bearings/inner race + 2.37 sprocket carrier + .424 cush pads = 14.5 LBS so BST saves 3.7 LBS on the rear for $1900

I know most people would say spend that $1900 on track days and I know they'd be right LOL.

 

Went for a few runs with the new setup, no regrets it feels much better. Mostly due to the gearing change -1 =1, power is more accessible and raw but more controllable somehow.

 

Tire weight differences are often over looked. Here are weights of Michelins I have used on my RZ500 track bike.

Weights of new tires:
Power One "street": F 8.5lb (120/60/17) R 11.9lb (180/55/17)
Power One Competition: F 9.4lb (120/70/17) R 13.9lb (180/55/17)

I could feel the extra rear tire weight of Power One Comps vs. Street, but it was made up for with the grip of the extra and softer rubber

 

Good info, I have a 120/60/17 Q3 front right now and it rolls right to the edge of the tire unlike most 120/70/17s I have ridden. I can see how that alone would make a difference on your set. That 2 extra pounds on the rear mostly from stiffer sidewalls?

I grabbed a set of track take offs on Craigslist for $100.
Pirelli Supercorsa SP V2 120/70/17 (9.3 new denniskirk) (9.05 LBS sides worn)
Pirelli Supercorsa SP V2 180/55/17 (13.4 new denniskirk) (11.85 LBS sides worn)
The sidewalls on the Pirelli rear are 1 ply and noticeably more flexible than the Q3s, Q3+ and S21

 

Remove the kickstand and get some swingarm spools and a Pitbull rear stand.

 

Id love to scrap the stand but Im pretty sure I cant live without it at the moment. Supposedly the 08 got a lightened AL stand but I havent weighed it. I do take my spools off in between working on the bike to save a bit.

 

Here is a little more info.

Props to @Bosarge22 for finding this link.

 

Here's what a 2015 Ducati Monster 1200S did to its well maintained OEM chain.

 

 

...and that chain looks like it's seen some mild neglect - about par for the course for drive chains.

 

There is nothing mild about that. Lol

 

@Bevo- A picture is worth 1,000 words and I wouldn't waste them defending this broken chain. It's very possible and LIKELY that there was a visually imperceptible flaw from manufacturing, but a warranty review will probably deny this one considering the corrosion around the pins.

If you have any doubts, just see post #17.

 

:laugh2:

 

You guys do realize that the chain pictured broke at the master link right? That is indicative of an improper installation. Most OEM chains are quad-staked at the factory which is a much better way of connecting a chain over an expanded rivet type master which is what they used in that pic.

 

It appears it's an adjacent link

 

The 2 most interesting 520 chains for 1000CC are the EK 3D GP and the DID ERV3 (IME). I got a chance to weigh the DID ERV3 520 and compare.

Stock 530 116 links dry worn 12K: 2286g (5.04lbs)
DID ERV3 520 116 links dry worn 5K: 1796g (3.96lbs)
EK 3D GP 520 116 links waxy new: 1761g (3.88lbs)

The DID ERV3 can be found for $120-$130 and the gold does look great when it is clean. I am obsessed shaving every rotating gram and I prefer the black so I will stick with the EK but the ERV3 520 is close in weight which makes it one of the best value performance mods you could do to any sportbike. $0.27/g saved.

Lame pics Ill get some better ones.

 

I came across a Sunstar countershaft sprocket to compare against the Renthal. They are both 520 15T steel with weight relief. The Sunstar is parkerized and the Renthal has a groove where the weight relief holes are and CNC lines on it. The Renthal is 13 grams lighter, because of the groove I assume. According to Renthal "CNC machined from case hardened and core refined 655M13 Nickel Chromium steel"

OEM 530 16T - 266 grams
Sunstar 39215 520 15T - 174 grams
Renthal 315U-520-15P 520 15T - 161 grams

 

Here are a few others that look good, actual pictures of that model, all 15T 520

Supersprox CST-1370-15-2 - SCM435 Carbon free steel
JT JTF1269.15 - SCM420 chromoly steel alloy
Driven 1013-520-15T - 45C case hardened steel
Vortex 3273-15 Nickel plated induction hardened steel
