before you get it. What other mods have you done to your bike? I ask because if you're doing this to lose weight, then there are a lot of other areas where losing weight might have more benefits and a higher bang per buck.

 

if i remember right, we wighed one at the shop and it was around 19lbs for the frame . rear frame dont know.

 

My Mods

09 R1
Nice Cycles Sterilgarda Fairings,BST wheels Michelin 2CT tires, Driven 520 conversion,Integrated taillight and turn signals,Flush mount front turnsignals, Akrapovic Evo Full exhaust, PCV, Sato Rearsets,ASV brake and clutch levers, Rear seat cowl,Doublebubble wind screen (smoked) GB racing crash protection, Frame sliders. oh and lithium battery

 

well sheot why do you need our opinion for this then? :lol

 

I'm really trying to find out how much the stock 09+ R1 subframe and tailsection weigh so I can figure out how much weight I will save with this mod

 

How about a nice 10 pounds? :dunno


:lol

 

Then that would suck cause double dog moto is advertising there all carbon fiver subframe/tailsection at 11lbs

 

For street?

 

holy jesus christ that's an expensive mod :scared

 

Also reducing weight from the tail (exhausts and/or tail) will invariably imbalance the bike and put more weight up front which should be compensated in some way

 

Remove the mirrors, and get carbon fiber crowl, front fender, and side panels, lol. Massive massive $$$$$$$.

 

Aye not necesserilly. But surelly if you also remove the exhausts from the tail and go side mount?

 

I'm not worried about it unbalancing the bike does anyone know how much the stock Subframe and tail section weighs on a 09+ R1

 

Don't worry, the balance of a bike comes from it's geometry and it's engine placement within the frame, lightening the subframe wont unbalance the bike, weight reduction is always good especially if the weight being reduced is high up like a subframe... I don't know if you ever found the answer to your question but I will know very soon as I am taking my subframe off ready to install a lighter one and will weigh both once removed.

 

If the stock subframe is 2kg (4.4 lbs), how much is the aftermarket?

 

If the stock subframe is 2kg (2.2 lbs), how much is the aftermarket?

Depends what you get. There are a few options. There is an alloy race subframe which I just got that is 1.395KG or there is the all in one rear end carbon unit that is a subframe and fairing seat unit all in one, it is like a rear carbon subframe in shape of complete rear end... I don't know how much that weighs in comparison to complete stock tail section but that is like $2000+ or there is the proper superbike subframe and under seat feul tank conversion, a carbon subframe housing a feul tank, actual tank is replaced by dummy carbon tank shape cover, that's the ultimate way to go but good luck finding it and probably about $3 - 4000 second hand.

 

Good look geting the DD tail I have been trying for ever now ive been in contact with belissimo the new owners of DD and they said they will eventualy start making them again sometime in the future

i would stay away from double dog products hell dont you remember the carbon fiber kickstand thread!....lol i went with a motoholders subframe on my race bike an 07 r1...total weight loss was in the neighborhood of 17 lbs with alien motion battery,and getting rid of clutter and using race tail....

 

I got the motoholders one, it's 0.7 of a KG lighter than stock 09-12 subframe, well worth it considering how cheap it is to other subframe options.

 

Yoyodyne! +/- $500 :crash

 

I'm looking at a motoholder subframe. are you happy with the buy?

 

Yep it's great. I only have 1 small grumble though. The subframe at the mount points is about 5mm thinner than stock, there is no mention of this buy motoholders. I screwed the subframe on and all was fine. I noticed later that the bolts stuck through the other side by a lot and thought it was odd. As a result I ordered some nice titanium race spec bolts from pro-bolt to replace the toques drive stock ones and counter the length problem... When I undone the stock bolts I had a shock. Where the stock bolts had gone through an extra 5mm due to the frame being thinner, it had pushed the un-threaded portion of the bolts through and wrecked the threads on my frame. Luckily a friend had a tap and recut the threads and my new corrected length ti bolts fixed the issue.

Hope this stops others from having the same issue.
