883 to 1200 conversion question

1/2

Hi
I searched for this topic, found some information but didn't answer the question I have. My question is,

I am currently riding my stage 1 883. I am pretty happy about everything except while riding at 110km/h on the country highway, I have to really twist hard to keep it at 110km/h. It has no problem keeping up, just I had to twist my wrist over a big angle.

My question is, if I get it converted to something like 1200 stage 1, without gear change, does that still help me at 110km/h? or the twisting angle won't change, just the bike become accelerating better?

Or it is a gear issue? I mean, suppose I can put 48 or Iron 1200's gear into my 883, it will help?

many thx

Odd. I'm a Stage 1 (pipes, air cleaner and Thundermax ECU) and have no probs at all on the motorway. If I twist the wick up she will jump to 130 without thinking!
Are you running stock ECU or aftermarket?

Sounds like you should just buy a quick action throttle lol
This one specifically mentions reduction in wrist strain.

I guess degree of twist is subjective. I have never noticed an issue, or perhaps I have subconsciously addressed it by adjusting by hand start position so that it always ends in the same position on all my bikes.

You have not mentioned what year your bike is oe if EFI or carb?
also 883 = about 55 cubic inch 1200 = 74 Cubic inch with the change in cubic inch you will get a good torque increase, as in general about 1 foot pound of TQ per cubic inch. as it's Torque that thrusts you forward till your past the Torque curve, horse power just gives you speed but can't really feel it like you can feel Torque. as they say torque is quick HP fast. the low gears are ok as easy on bottom end bearings & motor.
Also it's very hard to say what you really need just going off a forum post. really need to ride the bike to say where it needs improvement.

it's 2013 model I bought it second hand. the pipe is short shot. I think they are still Harley/SE stuff.

Hi, just wondering, is this to replace my current right hand grip? or it can be fit with my current grip? I am using "edge cut" collection grip on my both handlebar and passenger footpeg. G2 doesn't offer the same style on their website.
thx

It's 2013 model Iron 883 stage 1, should be everything Harley/SE brands.

Its just a throttle tube. Normal grips go on it.

I’m thinking re 1200 kit for my ‘05 Sporty (carby) too.
But, I seem to not have any problem keeping up at a buck thirty plus, without twisting my wrist off. Maybe it’s due to the great CV thing.

Just want the low end torque that a 1200 would deliver.

A sporty 883 can run at 100km/hr piece of piss. So if you find your twisting the throttle too much then check the tune.
Are you running an aftermarket ECU? Cause with short shots your gonna need something to boost the power they rob.

What EXACTLY are the stage 1 mods you have?

I bought this bike second hand. From what I can see, short shot for the pipe, and heavy breather for intake. The local dealer has the bike detail including the previous owner's. So I reckon the previous owner must have done everything at dealer, no fancy stuff.
100km/h is fine, just when it goes to 110 to 120, I had to roll my arm very hard.

I just had some reading from other forums, it seems its quite subjective thing, some people have this issue on other models too, some don't.

I reckon the progressive grip is the way to go for me.

micathia, the 883 should go hard enough. they have different heads than the 1200, but still should not run as slack as your saying it does. there are a few ways to go but up to you how much you want to spend.
good luck.

Torque is what you want for accelerating at highway speeds. Replacing your shit shots with the factory headers would be a good start

Until you know exactly whats on your bike your pissing in the wind and just guessing.
Ring the dealer and ask for an inventory of whats being done; key will be if the ECU has upgraded/replaced as that drives performance. Pipes and a Big Breather are useless without a new engine tune.
- Short Shots are crap for performance as well
- 110 to 120 on an 883 is an easy cruise (well that's the case on my Stage 1 883)
- A new hand grip is going to do squat to performance. Why not just adjust the starting position of where you have your hand on the grip to begin with.

Hi I check the website, it has two options
1) 7/8" handle bar conversion tube - 96 and newer
2) All 96 and newer HD model with cables - no-fly-by wire.

which one I should choose? Mine is 2013 Iron 883 with HD Chizel bar (z-bar).

This is giving me the chits.... your not listening to any of the advice presented.
Just buy the one YOU think will fit your bike and then ask how to retro fit the item that does not work, or better still you could email the company OR you could inspect your bike to find out what system it is (we call this Google). IF you decide to buy this then at least invest in a manual (we call these instruction books) so you know what to do.

I'm unsubbing from this thread

I’m not sure a quick action throttle is going to do what you think.
I’ve ridden an 883 a lot, commuted, blasted it around town.. was great.
But tried some longer distances on 110 freeways, it struggled, 883 is a pretty small motor with little up top add to that they are pretty undergeared. End of the day they only put out what 40-50hp? On a bike that weighs a fair bit for its size.

I’m not saying they’re shit, but it’s not dissimilar to driving a small 1.3 hatch on a freeway then expecting hard overtaking performance.

I have to disagree. My stage 1 883L easily cruises at 110km/hr and can nip up to 130 to pass cars etc with no problem.
I 'think' this is coming down to a tune issue.

Actually..... Plan B could be as simple as loosening the handgrip on the bars and rotating slightly forward. This would leave the hand in a more natural level position rather than bent at the wrist holding the throttle open. Would only take a few minutes to rotate it and test to see if its an improvement.
