It will be interesting to see if the G5 and B5 get the new fork treatment too or if increasing the trail is just an attempt to gain back a little more stability lost on making the head rake angle steeper.

From a manufacturing standpoint it wouldn't make sense to have two different configurations in production at the same time.

Parts are least expensive when a lot of them are made without changing the machine setups.

The export bikes are already different.  Different tires, different ECU/exhaust with the O2 sensor, different front wheels on the C5 (19" for IDM now), and I think a few other little things.

True but the fewer things that are different the easier it is to produce on an assembly line. :)

I found this quote on the Team-BPH forum about the new 2012 front fork.
The individual who posted it said it came from a review by  Adil Jal Darukhanawala from an article on zigwheels.com

"...the internals and their construction are all new. The revised geometry this brings in its adoption sees the trail hiked to 101.49mm from the previous 72.54mm while the centre shift of the forks measure 26mm at a rake angle of 26.09 degrees..."

Over an inch change in trail!  That' huge!  I bet it feels like a totally different bike.  Do you know if it's the same frame (head angle) and casquette?  What's the trail on a G5?

This subject needs to be investigated in detail, before coming to a final conclusion. May be Kevin M would be the right person to bring in the "factory perspective"
Or may be he is just waiting for all the brainstorming to end  ;D

Reminds me of an early '70s Kawasaki Big Horn (Big Hoax).  It was set up so you could mount the axle in front, or the center or behind the fork sliders.
They were horrible handling pigs. I guess Kawasaki couldn't figure out how to make them handle, so they left it up to the customer! I guess the customers couldn't figure it out, either, they didn't produce that version very long.

To clarify, the 2012 C5's (US) we got still have the leading offset front end. No change.
The 8mm change in pinch bolts started showing up in the last batch of 2011's.
To convert your early model to 8mm, we just drilled them with a hand drill. 2 minutes to fix it.
Maybe we should all mention where we are from as there are numerous differences around the world.

And there's not guarantee that the next batch of 2012's you get in will be the same.  The warranty explicitly states that they can make changes and improvements at any time with no obligation to retrofit existing bikes.

Ducati and lots of other manufactureres do the same thing.  You can have identical models from the same year with different parts.  I guess it's a combination of improvements and what supplier has parts at the time.

Guarantees? In the motorcycle biz? Please.
Yea, well you get used to that. So far, with the RE's the few tweaks we have seen have been for the better. The last military we got, the paint was much prettier than the first. nice bit of gloss, it looked deeper if that's possible.

Will a 19" wheel and tire fit the C5 without any modifications to the front fender? 

Just wondering, cost would probably too great for me.

Yes, mostly.  One person who did it reported needed to enlarge the holes in the fender struts a little as I recall.

And there's a kit: http://nfieldgear.com/enfield-store/c5-19in-wheel-kit.html

Why go through the expense of a new rim when some of available tires for the 18 inch rim have the same or very close outside diameter as what one can shoehorn onto a 19 inch rim under the fender?

You are right, it makes more sense to get a bigger tire for the front.  Thinking about a winter project of replacing with the Kendra K265  3.50x18 for both front and rear per r80rt's and some others suggestion.  I like the look of the Kendra's. 

Thanks Scott for the Nfield Gear link.  I should have looked there before I posted.

Arizoni, it was me.  I broke 2-3 of the 6 mm bolts, which was beyond absurd.  

I had a horrible highish (60 mph) wobble and found out the front axle wasn't pinched at all even though the pinch bolt was plenty tight.  I guess ample play in the front axle can lead to high speed wobbles, what a surprise!
