Woody's 21" vs OEM 19"

So, I won't go into details but I basically destroyed the cast rims on my GS last weekend. I will say I had a BLAST doing it though!

Now I need to replace my rims. The cost of OEM's vs. Woody's is basically the same. I don't do a whole lot of dirt and at 5'8" a 21/18 combo really isn't going to do me favors.

So, I'm going to stick with the 19/17 sizes but with one question: OEM's vs. Woody's.

Alternately stated: Tubes vs. Tubless. 'Cuz the Woody's need a tube on the front, minimum. I'm not big on tubes...but the BLING factor of the Woody's is darn hard to avoid!

One Day I will do the TAT. Not sure if that makes any difference.

Thoughts?

I got a set 19/17 done, superlace - billet hub, excel wheels. Per my conversations with Woody and Zack, they cannot make a 21" wheel tubeless (this the need to order a special built - HP2 front??) but can the 19" and 17" as I have had them do to both mine. Mounted the Tourances, sealed up easy with a bestrest minipump. I had no problems with setting the bead. For the rear they use a 4.00 width rim vs 4.25 as BMW does but it make no difference. Woody said that's the norm and BMW is the oddball on this. If you want to reduce the cost and delivery a bit, call them, as they may have access to a stock set that they can true up or may already have some on their site for sale. If you change your own tires with irons I'd recommend either stay with silver or be sure to use leather or similar when mounting to prevent the scratching. I went with the black (little extra $$ as they have to have these particular wheels colored) to be similar to stock. The can do either a very shiny (spend some time buffing them up) or the standard which is about the same as the OEM black wheels.

4.25" was supermoto standard width before the OEM SM bikes started showing up.

You're considering doing the TAT on the 1200 and you don't think you want a 21 up front?

I think it is all what you are looking for. For the front, if I had to buy new I would go 21" - just because of the better off road abilities and the fact that a 90/90 21" is much cheaper than a 19" front - the old R100 / R80 GS had 21" as does the F800 - so that speaks some merit of the 21" - tubeless can most certainly be done using a R100 rim but they are not nearly as strong as the Excel rim.

The 17" rear is the way to go - I considered the 18" for my 1100 GS and my 30" inseam and the good choice of 17" rubber made me stay with 17"

All that being said I have a Woody's 21" front and an OE 17" rear on my bike - 90/90 21 on the front and 140/80 17 on the rear - tubes on both ends. I am happy with the whole setup!

90/90-21 on the front gives you better off road abilities but at the cost of worse on road handling due to higher trail and smaller contact patch up front due to loss of 30mm width with a 90mm tread.

New Wheels!

Well, it's done. I received and installed my wheels from Woody's.



I did my first real ride yesterday, about 85 miles mixed freeway, secondary and gravel/dirt roads. I noticed a slight difference in the on road handling, the bike seems to turn in a bit slower and the Heidenau I'm running wants to follow rain grooves and tar snakes. Also not quite as stable at freeway speeds. In the gravel and dirt however, wow. Confidence inspiring is the phrase. Being the weekend before Christmas I didn't have time for a long ride but I can't wait to to an extended back country trip and see how the work. If your on the fence about a 21" conversion, just do it. The on road compromises are completely worth the improvement in off road ability.




Next up... fender modifications. Stay tuned.


Ed

Ed, your bike looks almost identical to mine!
A red GS with BMW tubeless 21" wheel....

Curious to see what you end up doing with the fender.
I got a chance to get one of those Wunderlich fork clamps for a very good price so went that route. But I didn't get the Wunderlich fender.
So far I cut a stock fender in half and attached the front half to the Wunderlich fork clamp.

I still need to make something for the rear half of the fender.

Post a pic, I'd like to see it.

I've got a cheep supermoto fender on order. My plan is to cut it to fit and fab some brackets. Won't have it till after the 1st of the year so we'll see how it works out then. Given the current weather here, i.e., pissing rain, riding without a fender isn't an option. The stock one clears the tire if just barely.

Sent Woody's an email yesterday to get mine ordered.

CANT WAIT!!!!

Merry Christmas everybody

Mike

UPDATE: So Zach set me up and I will be riding 21x1.85 Excel 7000 front and a 18x3.5 Excel 7000 rear. What I need to figure out now is, what tires?
50/50 I thinkin the Pirelli MT90 90/90-21 front and 140/80-18 rear.
90/10 Anyone using the Dunlop 606's? what size rear for the 3.5 rim 120/130/140? Other suggestions?

OK, so scratch my last comment on the D606's....just realized the 130 wont fit the 3.5 rim.

What it gonna be?
D908RR ($$$)
MT21's (different opinions posted here)
TerraFlex (havent seen anyone comment on these yet)
TKC 80's (had them previously and OK but not great, they were tubeless not sure how TT's compare)
Karoos (not a fan)

What else is out there? 140/80-18

Stutter...hope that doesn't offend MMMMMotorcycle {in my best Micheal Palin impersonation},

If you have the 18" x3.5 rear then maybe these:

http://www.bikebandit.com/irc-tr8-ba...otorcycle-tire

I had really good fortune with IRC on my KX 500, that thing ate tires like they were made of Big Macs....but not the old IRC M5B I think was the number....been along time. Worth a try at $84

EDIT I just did the conversion, that is too small.

If you are looking for REALLY serious off road here is your size
