Default 49mm Forks?

Morning Peeps - I'd like 49mm forks on my 2016 Custom (like the 48 models, for instance). I've read that some Dyna front ends will fit, though most seem to be narrower, 39mm. (I also remember reading that the hub needs to be 25mm - but I may be getting confused...)

In fact, the whole schimozzel is confusing me! Does anyone know which 49mm front ends will definately fit a Custom - with ABS & retaining the original wheel, etc.? Or is this a mod too far??

Cheers,

Chris

Hmmm, let me think. … Maybe the '48'?

Yes, thanks Folkie, that's very helpful...

I was hoping to get a Dyna front end as it's be a gazzilion times cheaper than a new 48 front end - the sliders alone are over £400/$500 each. If I could get a used Dyna front end, I could get it re-chromed/powder coated and, with a sexy adjustable fork kit (like Shenneba's gorgeous SE 45400176), I'd get new tubes & springs. (Though that kit does not fit 49mm forks - I think Ohlins do one, but I'd prefere a cheaper one.)

Anyway, I'll keep searching...

Cheers,

Chris

If it's possible to get a used Dyna fork, it may equally be possible to get a used '48' fork (crashed bike?).

That'd definitely be the easiest and most straightforward fit.

Yes, that's what I was hoping for Folkie. Unfortunately the 48 has only been using the larger forks for a couple of years and I haven't ever seen forks or triple trees from a newer 48 advertised. Here's hoping!

I have looked at Dyna front ends but I can't find enough information, erm, that I can understand, to tell me for sure which trees fit a 2016 Sporty, and which forks fit the axle.

More difficulter than wot I thunk...

Cheers,

Chris

Pages 66-67 of the H-D '2016 Sportster Models Parts Catalog[ue - in the UK]', 'Fork Brackets, Front', shows a good exploded-view line drawing of the three Sportster fork options: they are all significantly different. I doubt it would be possible to fit the 48 front end to another Sportster (without lots of grinding & welding - and careful re-design).

I can't see that, for the Custom in particular, the huge and beautiful handlebar riser would be mountable, practically speaking. Also, the Lows & Superlows seem to have a much wider fork spread than the others. (Although p55-56 shows the same front axle for all cast wheel models, except the Iron.) Who'd-a thunk it? Unless someone makes a full conversion kit to go from 39-49mm forks, for each Sportster front end option, I can't see it being viable.

My supposition that this may be a 'mod too far' seems correct. A shame, I suppose (if you're into 'first world problems'!).

Intersting investigation anyway.

Cheers,

Chris

The frame is the same, therefore the fork is a straight swap. You may have to go with the '48' riser.

More trouble than it's worth, IMO; but then, I'm quite happy with what I've got (1200CB).

Default 49mm Forks on a Sporty

Here's the last word on the Sporty 49mm fork upgrade: http://xlforum.net/forums/showthread.php?t=1609609

I used a Dyna Street Bob triple tree [mid glide] and Dyna Fat Bob Forks to convert it to dual disks. I'm running the late model 300mm rotors and 6 piston Tokico calipers off of a Hayabusa along with a Sportster XR1200 120/70-ZR18 front wheel. The post more or less explains everything I did in great detail. I recommend you don't attempt this unless you're a machinist or have access to a machine shop. I purchased most of the parts for this project off of Ebay.

Morning Redbeard - many thanks for your reply. Your fork thread is a fabulous resource - thaks again - and covers a huge amount of what I was wondering about. (I wasn't thinking about changing the brakes though.) Still, your sobering warning against attemting this project 'unless you're a machinist or have access to a machine shop' confirms that this is a job too far for me. A shame 'cos your Sportster looks great with the Dyna front. But much too much for me.

Thanks again for posting Redbeard: great fork thread & hugely informative (and an impressive project you had there).

Cheers,

Chris

Default Sportster Fork Upgrade

I recently purchased an 05 H-D Dyna Super Glide. It has a front end like that of a Sportster. I'm going to upgrade it to dual front disk brakes. This only involves purchasing a new right hand rotor and a new right hand slider so I can bolt on a right side caliper. This is more or less just a bolt on and setting up a new brake line with a splitting T and a new 11/16" diameter H-D master cylinder. I'll also install some Progressive Suspension heavy duty springs if they're needed. I've never had a Harley with a stock front suspension which wasn't undersprung. As a result the Harley would always dive excessively under hard braking. This is about all that can be done for these Sportster and Dyna front ends. I've got plans for a further upgrade which involves an 06 49mm mid glide triple tree along with V-Rod forks and upgraded front brakes. I'll make this into a post on V-Twin Forum. Here's a pic of my 06 XL883 with it's upgraded 49mm fork front end, XR1200 front wheel and dual Tokico 6 piston calipers. Here's a pic of my Super Glide.
