17" Front Wheel - 600 Mile Review

I picked up a 17" SV650 Wheel a few months back for $50 on ebay. Being I ride 99.9% street on my DL650 it seemed like a good conversion.

Installation:
installing a 03-06 SV650 front wheel is pretty simple
take the disc rotors of the stock 19" wheel and put the 17" wheel on.

Suspension/Tires/Rider
160# geared up
.90 Sonic Springs with 15w Fork Oil
Forks at stock height in triple trees
Bridgestone BT021 120/60ZR-17 Front & Bridgestone BT021 150/70ZR-17 Rear
Stock Rear Shock
Ride-On TPS tire sealant/balance

Initial impression
The first ride was interesting I had new tires, wheel size, the Ride-On was not spread thru the tire yet and at stock fork height. The 17" wheel is 2.5"-3" lower the the stock 19" wheel. I took a 15 mile shake down run. The front end felt a bit jittery compared to the 19" wheel with 20mm raised forks. The tires also felt a bit slick and wobbled a bit. Also the speedometer reads 10-15 % to hi as does the odometer. Overall I was regretting the change and wished I stayed with a 19" wheel.

1st Ride To Work
The tires were still in need of being scrubbed in. The over all the bike felt unstable and I was thinking of putting my old bt020 back on the 19" wheel over the weekend. The ride home was better. I was getting used the the new suspension geometry and the tires had around 145 miles on them when I pulled into my driveway.

The last 450 miles
WOW WOW WOW
The 2nd ride in the tires stuck to the road. I was taking a few high-speed sweeper that felt unstable at 80 mph at 95mph and the bike was planted. It was a bit windly on the way home that day and the bike felt 100x more stable in the wind. For the first time in 50,000 miles my vstrom felt safe in 20mph gusting winds.

Final impression
I can see now why many of the other "Adventure" bike come with 17" wheels. For riding on the highway the bike feels much much better. Of course off-road the 19" is better but I can swap that on with a hardcore tire and use the 17" for the street. I'm not a good enough rider the scrape the pegs thru the corners on the factory 19" wheel and a 2" link to raise the rear. Riders who "scrape the foot pegs thru every corner" may want to stay away from the 17" wheel conversion. High-speed touring, freeway on/off ramps and general commuting I'd say the 17" wheel is the best choice. The front end of my VStrom feel planted for the first time. Wind gusts, down hill turns (coming off a freeway interchange) and high speed sweepers are all easier to handle.

Good info, but maybe you should look for an SV front fender to mount on there as well.

Yep...

That fender has got to go!

But thanks for the informative post. This is a mod I am also considering.

(Edit: I see now you don't have riased forks.) You've set that baby on it's nose pretty good. No wonder you like the way it handles.

I think your bike is an excellent candidate for a steering damper. You have sharpened your front suspension a lot. At some point as a bike gets sharper and sharper, there is a risk of a tankslapper. You seemed to be saying in your post you thought your bike was more stable than before. It might handle great and feel great but it is very likely less stable than before.

If you had a big power motor and the front end was always getting light, I'd predict there would be a slapper in there somewhere to be concerned about. But a stock Strom is fairly slapper resistant and the Wee has modest power. A quickened Strom, who knows? And this isn't a mod many have done, so you may not be able to seek the wisdom of others that have experience with this.

I suppose if you are going to induce any instability, you'd feel it first accellerating over bumps when the front starts to get light. And I wouldn't be in a hurry to ride that setup over 100 mph, because if you hit some bumps at high speed you might find out in a huge hurry if there was any instability to worry about.

You could always post your mods and measurements on a Track day website or a racing website and see what the racers think of your geometry. They might know. You can also pay for a suspension pro in a racing shop to check out your bike.

Good luck with this mod. I think it is very cool. Be careful.

(Edit: sorry for the multiple edits. I find this mod very interesting.)

Did you ever correct the odometer error? Is the front wheel from a SV1000 the same?

I'm still looking into fixing the odometer. I know a 03+ SV650 Wheel works with a DL650. I don't think a SV1000 wheel will work
