19" front?

Anyone run a 19" front on their KLR?

I have an extra front hub because of breaking the speedo tabs on my original:

http://www.klrforum.com/showthread.php?t=13417

BTW the repair is still good.

I could just take my wheel apart and replace the hub but I'm thinking of going with a 19". I would like a wider footprint for road riding I think. Off-road is limited to dirt roads for the most part so I don't expect much difference. I know that the speedo will be effected but heck it's allready 10% off!

Thoughts?

They are 21" for a reason.....seems most dual sports are spoting these no?...maybe I'm mistaken..?
I would think that the only benefit would be for sand or deep sloppy mud havng a wider footprint....? The rest I'm not so sure about. On the street it may make more sense for handling....but I'm not that good of a rider to know the differences.

I think it's a personal choice and some just like the looks of it.....?

The tire sellection is much greater isn't it.....that would be my only good point for doing it....maybe?

19" Wheel for KLR

I did this mod to my '08 KLR to turn it into a street only bike. I also have a '04 Bonneville and it runs a 100/90-19 front and 130/80 rear. In comparing the wheelbase and rake values with the KLR, I saw that I could duplicate the Bonnie's good handling geometry.

I relaced the front wheel with a 19 x 2.15 Excel rim from Buchannon. Buchannon sent me a set of SS spokes that were custom for for this rim using a '08 KLR stock hub. Total was about $350. The spokes were exactly the right size and the rim laced up very easily. I went with the 2.15 because the rear rim on the KLR is on the narrow end for a 130/80 (it's the narrowest rim that bridgestone recommends for that size tire). The 2.15 rim is the narrowest that bridgestone recommends for a 100/90.

I fit Bridgestone BT45s front and rear.

I was concerned that going to a smaller front wheel and tire would change the steering geometry, so I measured all tire ODs (stock and motarded) and figured out that I needed a slightly longer front spring spacer (1.0" as I recall), so I cut one from plastic pipe and swapped it out with the stock steel spacer.

The result is a good handling street bike. Since my KLR will never go offroad, I'm happy with the result.

Of course, since I'm obsessive, I hunted down a used front hub and relaced the stock rim to it so that I could get the bike back to stock if need be.

Thanx for the info.

I'm wanting to go with a 2.5" rim for a better tire fit, shouldn't matter about the width of the back right?

What guage spokes did you get? I'm not understanding about adding pre-load to change the geometry, that would change the weight bias yes? I think I want a bit more weight on the front and a larger contact patch that's why I would do the conversion.

I'm still on the fence about this if it's worth the cost. I do need to change out the original hub. There's a chance that I won't be able to just swap hubs with the stock spokes (in case there's some frozen up).

Rim width: The Bonneville rear rim is wider than the KLR rim (for the same size tire), so I went with a narrower (2.15) rim than the front rim on the Bonnie. The tires (front and back) on the KLR are rounder in cross-section than they are on the Bonnie. If you go with a 2.5 front and a stock rear rim, you will get a flattish profile on the front and a roundish profile on the back. That is what I was trying to avoid.

Spokes: I used the OEM guage spokes (4.0 mm IIRC). The spoke size is driven by the hub - Buchannon drills the wheels to fit the spokes chosen.

Preload: To maintain the steering geometry, I needed to raise the front end 1". By adding a 1" spacer it raised the whole front end up 1". It's not quite the same as adding preload - the fork spring was compressed at rest with the stock spacer, adding a 1" spacer just raised the front end 1".

BTW, it's worth it. The bike handles very nicely.

19 "

hey

yes 19' front ,,is great =done to one of my klr's..
rides great/better on road and off ,,as have A LOT wider contact point..
yes more dirt bike/dirt tires can be found in a 21".. =not many full knobbies in 19",, with a higher price too..

as i was told ,,know what "Type Of" tire you want to run...knobbie/street/etc..

i run 110/80/19 front a 130/80/17 rear,, with 50/50 tires ,,works great !!!
even seems to stop better!! = thats with stock brake rotor...

FYI -FACTS::this does change your speedo read out,, is not correct now ethier...
just need to get use to the difference(know how much it's off) or get another type speedo..
also drops handlebar = sitting position..

Gonna revive an old post as I'm doing a 19" project in February. I ride 100% street and am currently using Anakee 3 tires (130/80R-17 rear). The 19 x 2.15 is good for the 100/90 tire but the 19 x 2.50 would also fit a 110/80R front, in addition to a bias 100/90. Would the 110/80R tire be too wide of a match for the rear 130/80? My thought is front/rear radials would be nice on the road? The 2.15 rim can be had for a bit cheaper too though....
