FYI, G2ergo.com's YZF-250 quick-turn throttle works on the CBR250R. It's $70 but is machined from aluminum and you can swap out the throttle cams later if you want. After loosening the throttle cables it was a direct swap and reduces throttle rotation quite a bit. I can now roll it wide open without my elbow dropping too much, which is beneficial in the twisties since it doesn't throw my body positioning off. Here's a link:

Do you move your elbow when you throttle?

Do you move your elbow when you throttle?

I do but I have one hand and the prosthesis I made does not have that type of wrist motion.

 

[tollarja]

lol, get 'em Aufitt! Thanks for sharing, I may want one of these.

G2 Quick-Turn Throttle Tube

I was just thinking today, that is exactly what this bike needs. With my biggest gloves on, it is hard to get WOT. Even in summer, I only grab about 7/8ths. I probably won't change it, because I may want to teach some newbies (and I'm cheap and lazy,) but I don't need that really long pull.

Interesting product, too bad it's $70..

 

[SmBkRdr]

Yeah, $70 isn't cheap, but there are other, more affordable quick-turn kits out there. Someone just needs to call the manufacturer and see if one is compatible.

Normally my elbow doesn't move when I roll the throttle WO, but that's on 600s etc. with 1/4-turn or less throttles. The CBR's throttle turns quite a bit further than that, and when going from off throttle to WO (without taking a moment to re-grip) my elbow does in fact drop quite a bit. When you're cranked over in a turn with your knee on the ground its beneficial to not have to worry about regripping, so I installed the G2 tube.

The ninjette forums have discussed a similar problem there. The solution was to superglue a nylon zip tie around the throttle tube to pull the throttle cable faster so WOT is easier. I have applied that to another bike changing it from a 50% to a 25% throttle for pennies.

For those on a budget a tube of superglue, 1 nylon zip tie and some time may be a solution for less wrist twisting.

That's a solution that I had consdidered, but I don't like the thought of the zip-tie coming loose and causing the throttle to hang up. I also thought about building up the throttle cam with epoxy. In the end I went for the E2.

I cant speak for others but what I did does not come loose (1 year or so of use), if it did you would have a couple inches max of zip tie around the throttle tube. I am unsure that it would cause a hang up but I can see that it is a possibility. Super glue works by melting the plastic together, which creates a fairly strong bond.

Interesting gizmo.

I always tell newbies that the right hand is suppose to be a rheostat, not an on/off switch but the 250 may be the exception to the rule

I run g2's on my MX bikes and I love them. I just may have to get one for the little bike now.

The engine's meager output is the rheostat!

Cornering requires precise modulation and not being choppy on the throttle.
Just checked it on my bike its about 1/6th closed to fully open.

Mine only moves about 1/4, in fact just a bit less.

Holding it against the stop is the opitome of not being choppy

Whatever the actual rotation (I didn't measure it before) I found it to be too much. I dig the G2, as it reduces the rotation appreciably.

What do you tell people that do not have a right hand?

 

[Metalstorm]

What do you tell people that do not have a right hand?

I tell them to find a bike with a left hand throttle and apply the rule to the left hand

 

[trixter]

but I like the throttle on the right side
