Lol, plus your bike is tall enough that you would need one of those little platform boots like in the Pee Wee Herman movie

The Kawasaki Eliminator BN125 uses the same front hub as the Zong/Viva/Roketa DB-07A/Shineray. However, the Kawasaki Eliminator employs a 17-inch front wheel. The speedometer sending units on all these bikes appear to be identical, but they probably use different gearing inside those units. I wonder if the speedometer on Recracer's Viva is accurate, or ten percent "optimistic," as is mine? :?:

It will be a while before the viva is out on the 18" . However with the 21" front checked with a GPS at 67 mph on the gps, speedo read very close to that , i was pretty suprised how close it was . maybe 1or2 mph fast .

Based upon your experience, Racer, it seems to me that Allen (Kato) is correct; the Chinese speedometer sending units for these particular motorcycles are all geared for a 21-inch wheel. Therefore, my Zongshen speedometer sending unit is probably identical to the Viva/Roketa DB-07A/Shineray unit. I know from personal experience that you will discover your 18-inch, front wheel will cause the speedometer/odometer to be ten percent "optimistic."

Good to know. I thought my Zong's speedometer was optimistic, that it was not a 70 MPH+ machine, 5 MPH faster than Q. Maybe I was only doing 60 in the 70 zone when I got creamed and the speedo was reading 65-70? :(

My Zong's speedometer is definitely ten percent "optimistic." However, it seems most motorcycle speedometers share this same characteristic. :roll: I would'nt be surprised if the QLink's speedometer is also slightly "optimistic."

The streets here are still covered with snow. :( However, if the snow continues to melt, I might get to test ride my new wheel later this week; I am keeping my fingers crossed!

Good point on Q's speedo, Spud.

You weather looks cautiously optimistic, but don't hold breath...

I won't be holding my breath, brother Bill. They have a saying here; "The only people who predict the weather in Idaho are fools, or newcomers!"

I certainly hope your hand is continuing to heal; I still pray for your complete recovery.

My open wounds finally healed last week, so I'm grateful for that. Right hand doing pretty well. Some significant loss of function, primarily with grasp on the left hand. I'm going to physical therapy this afternoon. I expect it will hurt but help. I'll do whatever I can to get full function back. I'm only 45!

I am very glad to hear your open wounds have healed, Doc. I know the PT is painful, but keep up your good spirits!

The snow in town has melted a little, but it might snow more tonight. :( Therefore, I still patiently await the opportunity to test my new, 21-inch front wheel. :roll: In the interim, I must content myself to look at photographs I took in late October, before the mountain trails were gated off.

Congratulations, and welcome to the Cult of the Zong! As we say in The Cult, "Resistance is futile, you will be assimilated.

Today the snow melted some more, and the temperature climbed to plus 40 degrees Fahrenheit; therefore, I had the opportunity to take my Zong for a 65-mile test ride I am very pleased to report my new, 21-inch, front wheel handled superbly!



The larger wheel seems to soften the bumps, even on the pavement. Also, I can now perform low speed maneuvers more smoothly, and easily. Braking was excellent, even with a new brake rotor. Also, my Zong feels very stable, and solid, while turning corners at highway speeds. I also noticed both low-speed, and high-speed handling are even more nimble than before! I am extremely pleased with the final results.



My complete front wheel, including tire, and brake rotor, weighs the same as a complete, Lifan 200GY-5 front wheel. Both these wheels weigh about ½ pound less than the stock, 18-inch, Zongshen front wheel.



As I was riding, I stopped to admire several local residents, grazing in the fields.



Pausing briefly between bites, Mr. Ed told me he liked the modifications I had made to my Zong. I always appreciate the comments of anyone possessing good, old-fashioned horse sense!



I eagerly await the passage of winter. I truly look forward to riding in Idaho’s mountains next Spring with my new, 21-inch front wheel.

Hello Spud,

Will the Roketa DB-07A(RSX-200E)(LXY), 21" front wheel fit the Zong Sierra 200? You mentioned you purchased one in '09 but ended up lacing another one yourself. Did the Roketa wheel not fit on your bike? Did it come with the hub and the brake disc? I am thinking on ordering one to replace my original front wheel for a 21". The problem is that with an 18" on the back, and the same on the front, I am constantly sliding forward on the seat. Maybe the bike was not designed to be on supermoto configuration. So, i am hoping that with a 21" on the front, the seat will be better level.

Thanks for you help!
