Has anyone figured out a way to lessen the force it takes to turn the throttle?

I watch guys on other sport bikes that can blip their throttle with 2 finger tips.

Remove the 'noid for starters. Make sure the throttle bodies have a well lubricated and clean set up.

I've been looking for a really good aftermarket throttle/cable assembly for our bikes and haven't found one.

noided since day one. Will have to go in and lube and clean the throttle bodies.

The throttle for the 1125r is very stiff. I've always twisted Ducati, Honda and other throttles with significant envy -- they are so light, so easy, never hang up, etc. I share your desire for "something better".

Even brand new, the controls on the 1125r are very heavy.

I use the inside of my thumb to "roll up" a little bit of throttle when on the brake, so it's something you might try.

total of over 20K miles on an 1125, and both of them were stiff.

I just don't really understand why it needed to be like that. I'll give the thumb trick a try.

Might be a look/see project this winter.

the stiffness is due to the amount of air flowing past the butterflys - the springs must counteract the air flow at WOT....gotta close those throttles some how - especially if the rider falls off...
if you increase the dia of the twist grip it will give you greater leverage..I use Grip puppies:
http://www.casporttouring.com/cst/motorcycle/GRIPP UP/GPSMALL.html
...some of the rice burners are fly by wire - you're not opening any butterfly valves or counteracting any springs - just telling an electric motor how far to open the throttle valve.
as far as to quality of the twist grip - might want to source one from a RC51/TL1000/DL1000...I've installed a throttle tube from an R6 which makes it a "fast" throttle (1/5 turn) and the less rotation with the larger dia grip ( grip puppies) may help your problem....it works for me.

lubing it up helped-that really sounds wrong.

Interesting grip product.

There are plenty of bikes out there with big throttle bodies that don't have the heavy duty springs we have.

Yes I have figured it out.
I masturbate frequently thus improving my forearm and grip strength, this lessons the related drag efficiency in the the throttle giving me that it aint so hard to do anymore feelin

well there are some great suggestions here Andros. from cheap to more expensive. for me keeping the bike properly maintained included keeping the throttle linkage, cables and so forth cleaned clear and lubed.

i came from the cruiser world and the kuryakyn iso grips are what i used so going from those to the stock grips on a sport bike was quite the transition. something that was suggested here was using baseball bat grip tape wrap or tennis racquet grip wrap. i think i am using baseball bat grip wrap that has a cushion foam core. it's cheap like $8/side and is easily replaceable and comes in colors if you're so inclined. it helps two fold; making the grips larger in diameter and provides the softer cushion grip.

the larger diameter does two things; gives your more leverage and make the grip easier to hang onto.

hope that helps.

I have used bicycle bar wrap. It is available in many colors but has a nice grip surface.

I honestly wonder if traction grips would help there are some similar grips available to the traction style but I haven't found em yet?

Bbear try these - i used these under the grip puppies - kinda like golf ball pattern with a "barrel" shape has very deep "dimples"...even seen some Beeemr types switch to 'em

squirt some H-D brand Chain Lube down the throttle cables. This should be done annually or every 5000 miles. on every motorcycle with throttle cables (except those with cruise control actuators on the cables)

Early this spring I took mine apart lubed everything and rerouted the cables it was a marked improvement, but they are still really hard compared to the say speed triple my friends wife has.
Nuts: Thanks I will look into them, there was a grand tour usa by sunline I think that were almost the same but they to are discontinued?
