48mm Showa Kashima Fork Help

[redwillis]

I bought a pair of forks for a project because they had black anodized lugs. They are 48mm lower legs, 53mm upper clamp, 58mm lower clamp, 37.5" long.

I have no idea what they are from. The lower lugs say "KRNL" and Showa.

I need to buy an axle for them and a brake caliper but I can't find anything similar to identify them.

I also need to lower them 5-inches using a spacer and shorter springs.

Looks like Showa twin chamber around 04/05 at the oldest? Honda? Don't know anything about air forks. Should have asked the previous owner what they were from.

Show the caps ?

[redwillis]

Hopefully this helps.

I really want to start taking these apart to see how to lower them.

I've looked at those but they have different lower axle mounts. They have an extra lug on the brake side.

I need to make sure I get the proper caliper too

The PO had no idea what they were from except they had Kashima coating.

They look RM to me.

But showa are 47 till 2010

Definitely 48mm. Did Honda make a special edition CRF that had black axle lugs and Kashima coating?

[redwillis]

The reason I ask is because the only picture I can find of a CRF with Showa forks and black lugs is this one. It's a CRF250R "HRCmodel" from 2007.

[redwillis]

And another one of a bike owned by Ashley Fiolek, who is that deaf girl racer, with the 2010 CRF

showa 47 from crf 2004 to 2007

47mm the 48mm are 59 54 in the clamp

But showa are 47 till 2010

This is me bowing to superior knowledge.

Hrc are not for sale

They look like a kit fork

They made a kit and b kit ,b kit are normally just fancy coatings std sizes

A kit can be different externally and internally

Then you have factory or works forks that are only for factory riders or teams

[redwillis]

Maybe I should ask what the stock axle size is for a 48mm Showa? That is what I need to find on eBay. I will order a seal and bushing kit for "48mm Showa". The parts guy wanted to know what year and model but probably doesn't matter.

I thought I measured 58 and 53 for mounting but will double check.

I have a Brembo caliper coming, so hopefully that bolts up.

I plan to lower the forks by 5-inches. Okay to cut the springs and add a top out spacer?

[redwillis]

So order "2008 CRF250R fork service kit"?

Now it looks like starting in 2011 CRF250R had 48mm Showa, before that was 47mm.

2010 CRF250R was first with 48mm Showa but the inner cap was different to what you have there and that is a Honda part number on the axle lug for sure. Think someone has built up these forks with a few parts from various Showa forks. The inner caps are like yours on 2012 onwards Honda 250 forks or maybe it was 2011 not sure.

[redwillis]

Good place to buy bushing and seal kit?

[Framebreaker]

The coatings are not stock.

The upper outer tube dimensions you gave are 47mm forks.

The caps look like 08-09 CRF250, no newer than '09 and the lugs are 2009 CRF250.

Pretty sure the lugs went from MENF in 2008 to KRNL in 2009 and the lugs for the 48mm forks are KRNM and so on.

Either way, these are Honda Showa forks. A CRF250/450 2005-2014 brake caliper and 2005-2016 axle should work fine.
