Is there anyone offering engine performance parts yet for the 1125? Heads, larger cylinders, cams, hi compression pistons, etc.? I did check with Henry and aside from the Race ECM there isn't anything | ||
| Endoman33 |
haven't heard of anyone yet | ||

who erever is building the race parts for the 1125r will have them out soon i would think | ||

Yes, there is a future to this but it won't be easy to acquire. Most definitely, once available, you won't acquire it via public forums. | ||
| Easyrider |
yep we do www.twinmotorcycles.nl only on holiday from tomorrow until the 7th of september, shop is closed. I make 143 HP with our race exhaust and programming the stock ECM on a stock bike. For the street customers enough to handle. What do you want to do with the HP? drag or street racing or fun.. | ||

On the RR, Buell has these neat wire mesh throttle intake covers. I think they replace the air filter. Any word on this? (Message edited by clarkjw on August 12, 2009) | ||

I got a little excited when I saw the motor apart. I didn't see anything on the site other than the ECM tune and exhaust, not what I'm after. (proverbial, been there done that) Heads, larger cylinders, cams, hi compression pistons, etc.? That is the direction I thought the article was going when you were claying the heads to check valve clearance. Drag racing is the direction I'm leaning with a touch of fun. I have a motor coming and have been in contact with shops to tear into it to see what they may be able to do. (Message edited by puzzled on August 12, 2009) | ||

That is what made me think we won't see any trickle down from there. Now the RR revs a little more and makes a few more ponies. I'd like to know how that was achieved. The 1500 extra RPM would be real nice. (Message edited by puzzled on August 12, 2009) | ||

puzzled, how much can you spent and how fast you want to go.. Mail me for the amount on dris @ twinmotorcycles . nl, There is more but nothing standard yet.. It will happen. | ||

The RPM issue has been touched on here, and someone did the math as far as piston speed, which of course is the limiting factor RPM-wise. Seems like the 1125 is just about at the limit there, so without some really exotic bits and pieces there's probably not a whole lot left. BUT: The guys on the cutting edge of tuning and exhaust are getting damned close to 150 hp at the wheel! R | ||
| Easyrider |
carbonbigfoot, the first thing we need is a complete new fueling system. The stock system can not handle more the 11000 RPM.. | ||

Puzzled - Pistons are available now. Go to any piston manufacturer with a spare piston in hand, tell them what ratio you'ld like and give them a coupla weeks. Easy as that. (I'd guess one could get a used up piston from a racer somewhere) I just had a set of pistons made to my desires for a car engine I'm working on. The 1125 piston isn't magic. The skirt design has been run in cars for a coupla years now. AND...being very similar dimensionaly to a small block Chevy..those forgings are easily available. Mike | ||
| Puzzled |
1_mike What I ran into with having pistons made is the manufacture wants you to take a set amount. With my drag car taking 8 is no problem. Taking 8 for a bike that needs two is a problem. Than again maybe economic times have changed that and they are willing to cut a pair.  Once the motor is here and in my hands I'll be able to see what is required. Currently I'm doing my leg work to determine my direction. | ||

The RR is spinning higher than 11K so I'd be curious as to what they are using for a fuel system. What are we talking here, injectors, fuel rails, fuel pump and whatever manages the injector rate?

That HP range is ok. Like I have said before, I want inline four HP out of my Rotax Twin. Why? Because I can. (or at least I'll try and this is still less than buying a new Duc ) (Message edited by Puzzled on August 12, 2009) | ||

the guys @ twinmotorcycles mapped my bike and i ran 10.00 et all day last weekend and raced rice burners never lost once they no there stuff i trust them with all my work  | ||

152+ has already been done @ the rear tire in the states on an 08' 1125R  ...I'll let that gentleman post his pre/post dyno if he wishes to. | ||
| Slypiranna |
Aftermarket pistons ARE NOT currently available or paid for. I have already talked with MANY on the inside and outside and NONE are ready to commit to the tooling required for such a limited market. This isn't a SBC piston. The 11 piston IS unique and requires a lot of $'s to tool up for from an aftermarket standpoint. Please stop dreaming and keep to facts. B.S. gets old quick. | ||

Easyrider; what advantages can we expect from a full system version of the torque hammer over the slip-on? Thanks! - Oops... wrong thread! (Message edited by T_Man on August 12, 2009) | ||

sly, can u elaborate on what was done to said bike, to produce that kind of power?? THANX, Jake | ||

I have been told by someone claiming to be "in the know" that just the race pipe(or equivalent) milling the heads and re-timing the cams (with a prerequisite dyno- tune) will give you an easy 150 at the tire. It seems that cams, bigger airbox and such are available now, a-la 1125RR, so if you have a race license, I suppose, but don't know, that may be possible, too. I'm sure Henry Duga knows a lot more than me... (Message edited by bigblock on August 12, 2009) | ||
| Puzzled |
Bigblock, I like your train of thought. That is why I called Henry after the dealer show and was told there isn't anything available yet. I'm not opposed to milling the heads. | ||
| Ridenusa4l |
anonymous stated in a previous thread (i believe) that the rr is around 160rwhp, but it also has titanium valves and race cams, per what i remember reading, also the larger air box, etc... But with enough money ANYTHING is do-able lol...hell puzzled just put a turbo on it and call it good lol...just a thought  Jake | ||
| Mrbikle |
im pretty sure my local shop decked their 1125 that they race. With exhaust and all that though they only put down 142....i put down 140 on the same dyno with just an OSB tune, lol. | ||
| Puzzled |
Ridenusa41 it is funny you say that. I turbo'd my Busa and it was stupid fast. Hmmmm | ||
| Ridenusa4l |
exactly now imagine that with a 54.5in. wheelbase hahahaha  Jake | ||
| Bigblock |
I think re-timing the cams, if you run the stockers(doesn't seem to be much choice right now) is an important part of the equation... I have no idea what the proper specs to dial 'em in to are, though... THAT might be a good question to pose to Mr. Duga... |
