View Full Version : RX3 Rear Wheel Rebuild with Warp9 Rim

I have changed the rear tire 3 times on my Zongshen RX3. The first time I got a flat, and seized the opportunity to switch from the stock rear tire to the Shinko 244 tire in size 5.10-17. Because of the very wide, 3.00-17 rim, and the sharp edges of the steel rim, I never had a more difficult time removing a tire from a motorcycle wheel. :wtf: Also, even with the sprocket carrier removed, the rear wheel was very heavy. :tdown:

The second time I got another flat, and the Shinko rear tire was even more difficult to remove from the steel wheel than the stock CST tire. >: Here is a photograph of the stock rear wheel, with the tire removed.

Since removing the tire from the wide steel rim was so difficult at home, I knew it would be even more difficult to remove the tire during a roadside repair. :ohno: Therefore, I decided to rebuild the rear wheel with a Warp9 alloy rim, size 2.50-17. :) The narrower rim facilitates removing the tire, and the alloy rim has a more rounded edge, which doesn't dig into the tire bead. In addition, the smaller, alloy rim is lighter in weight, and the size 2.50-17 rim also allows mounting a smaller, 4.60-17 tire. The smaller tire lowers the seat height about 1/2-inch, and also weighs less than the larger, 5.10-17 tire. ;)

Here are photographs of both sides of the Warp9 wheel after I remounted the Shinko 244, size 5.10-17, rear tire.

The size 5.10-17 tire is great for bearing the heaviest loads. However, I always prefer to travel light. Therefore, as soon as this rear tire wears out, I plan to replace it with a Shinko 244 tire in size 4.60-17. Unlike the wider stock rim, the narrower, 2.50-17 rim will safely accommodate the smaller tire, which is designed for a size 2.15-17 rim. Nevertheless, the size 2.50-17 rim also allows me to revert back to the wider, 5.10-17 tire, if I ever decide to burden the bike with much heavier loads. :)

Wow I am guessing replacing both the front and rear steel wheels with aluminum should give you a pretty good performance increase. Do you have plans to do the front?

I can lace a Warp9 rim to the front wheel for only $85.50, if I use a 10 percent off coupon at Rocky Mountain ATV/MC. :)

I might do it, but I'm not in any rush. There is definitely less benefit, and less incentive, to replace the front rim compared to the rear rim. ;)

Spud just curious again do you balance your new rim and tire?

No, I don't balance knobby tires mounted on dirt bikes, dual sport bikes, or adventure bikes. I have never felt the need to do so, since my bikes don't perform like sport bikes, and I don't notice any adverse effects from not balancing the tires. Also, knobby tires always wear a little unevenly, so I don't think the balance would last for long. I think the most important maintenance tasks for off road wheels is keeping the spokes tight, and the wheel true.

Excellent idea, Spud.

While you had the wheel off, did you examine the cush drive? Any signs of cracking or wear?

Thank you, Weld. :)

Yes, I always examine the entire wheel every time I change a tire, or do any other wheel maintenance. The Zongshen hub is built extremely strong, and I think it's almost impossible it would ever crack. :) I did not notice any signs of unusual wear. These Zongshen bikes are built tough to last for the long haul. :tup:

I just wish they didn't bathe the brake rotor bolts in loctite, and install them with an impact driver at the factory. :wtf:

All my motorcycles are off road bikes, with knobby tires. I have installed rim locks on both wheels for my other bikes, and I will probably do the same with my Zongshen RX3. Putting a rim lock on the front wheel prevents the front tire from leaving the rim if you get a flat tire while riding the pavement. :wtf: Putting a rim lock on either wheel prevents the flat tire from ripping the valve stem from the inner tube.

An added benefit of the size 2.50-17 rim is the availability of rim locks to fit the rim. :)

It might exist, but I have never seen a rim lock which fits a rim larger than 2.50 inches wide.

Spud you didn't happen to weigh both sets of rims to see how much weight you took off did you? I put on the 5.10x17 also and noticed it does rob some power, especially on long up hill grades. But it is nice in the rougher stuff for protecting the rim and tube when impacting sharp rock ledges etc. rj

Thank you, Huck. I am pretty sure the front spokes are all the same. If you send a single spoke to Buchanan's, they will help you to measure your 19-inch hub, and create custom spokes for the new, larger wheel. :)

I did not weigh the steel rim, but it is significantly heavier than the narrower, alloy rim. ;) The entire wheel feels much lighter with the Warp9 rim. :) After I switch to a smaller rear tire, the wheel will get even lighter. :tup:

The problem arises after you spoon both beads over the rim, and you either attempt to push the tire over the rim, or attempt to pull the rim out of the tire. The wide rim doesn't want to exit the tire. :ohno: Also, the sharp edges of the steel rim bite into the bead of the tire and grip it, instead of allowing it to slip off.

In addition, the wide rim also makes it more difficult initially to break the bead of the tire from the rim.

I went for a 110-mile ride today. After I returned, I examined the new wheel, and all the spokes were tight. :) Therefore, I am confident the wheel is sound, and I will check the spokes again the next time I remove the rear wheel. :tup:

Here are a few photographs from today's ride, showing the new rear wheel from several different perspectives.

Spudly, Did you use the stock rear spokes on the Warp9 rear wheel build or did you need to have Buchannon make up the correct length spokes for you. Also....have you noticed any acceleration gains with the lighter rear wheel and tire. And......are your running a 13 or 14 tooth countershaft sprocket? Thanks for your feedback as always. :clap:

SpudRider
08-06-2015, 02:07 PM
Yes, I used the stock rear spokes for the Warp9 rim. I only needed to purchase a 2.50-17 rim from eBay. :)

The rear wheel is much lighter, which makes it easier to change tires, and mount the wheel. The wheel will get even lighter when I switch to a size 4.60-17 tire. :) The bike handles great with the new rear wheel, and the unsprung weight of the wheel is much less. My butt dynamometer is pleased with the results, but I don't have any scientific data to corroborate an improvement in acceleration. ;)

I am running a 13T C/S sprocket, and it definitely has improved acceleration. I would love to test my RX3 versus a stock bike to note the difference in acceleration between the two. :)

Spud,
Have you removed a tire from your new aluminum rim? Was it "easy"? Easier than the steel rim?
The reason I ask is that the aluminum rim looks like it has an extra rib a quarter inch or so inside the flange. I think I've read that the rib is for tubeless tires to hold them on better in low pressure situations.

Spudrider, I'd like to rebuild my wheel, but I'm trying to decide whether to do it myself or have it done professionally.

Is it something a total noob can do? or should I get a pro to do it? I'm especially worried about warping the rim and screwing up the dishing.

detours, I've built up a Warp 9 for a rear on my KTM and it not too difficult if willing to spend the time and be methodical. I would say it's certainly easier then building up a bicycle wheel. I have every intention in building up an 18" rear and 19" front for the Zong soon. I was hoping to have it done before the Baja ride but that just not going to happen in time.

I'll try to past some pics tomorrow.

No, I haven't changed the rear tire since I laced the new rim. However, the rear tire is almost worn, so I will be changing it sometime this spring. ;) I am confident removing the rear tire from the rim will be easier, since the new rim is much narrower than the old rim. :)

http://i442.photobucket.com/albums/qq146/spudrider/Zongshen%20RX3/GEDC0745_zpspic238s6.jpg

The Warp9 rims do have a very small rib inside the flange, but I don't know the purpose of the rib. This rib is perhaps one millimeter high at most, and appears to be corrugated by the machine tooling as the rim is bent into shape.

Detours,

If you do some research on the internet, you can certainly teach yourself to lace and true a wheel. As 3banger states, you should take your time, be methodical, and make small adjustments. I also recommend you invest in a good truing stand. :)

If you don't feel like doing the job yourself, for whatever reasons, it is best if you can find a local shop to do the job. Having the job done locally will allow you to save a lot on shipping costs, instead of sending the hub to Buchanan's, or another wheel builder. ;)

I love the Shinko 244 tires; they do a great job on the RX3. They also last a very long time. I have ridden a little over 13,000 miles on my Shinko, 244 rear tire, and it still has a few miles left in it. :)

My Kenda, K270 front tire lasted almost 13,000 miles before I replaced it with a a Shinko 244. The K270 would have lasted even longer if I had flipped it every 4,000 miles. ;)

Hey Spud....need your feedback on this. I just laced up the 17" Warp 9 rear rim this afternoon. I am a bit concerned about the spoke length using the original RX3 spokes.
I have it trued up but most of the spokes have about 3/16" of thread showing above the nipple. This equates to about 6 or 7 threads on the spoke itself.
Can you tell me if this is about the same result that you had and if so....apparently you have not had any issues. Just concerned about not having more threads engaged in the nipple. Thanks for your feedback!

rjmorel
01-26-2016, 09:06 PM
The rule of thumb for us machinists is that in steel anyway, once your threaded in more then the length of the diameter of the bolt, you will twist the bolt in 2 and not strip the threads. So on a 1/4" thread once you have more threads engaged then 1/4" it should break bolt in 2 and not strip the threads. Brass may be different ???? rj

Yes, I got the same results. :) I think I might order some custom spokes from Buchanans, which are a little bit longer. However, I have not had any problems with the stock spokes. ;)

01-29-2016, 07:52 PM
Okay, so I went ahead and contacted Buchanan's Spoke customer service to get the straight skinny. They said that if the threaded portion that is engaged is 1.5 times the diameter of the threads....maximum strength has been achieved.
So in the case of the RX3, the spokes are 4mm diameter....so any engagement more than 6mm should be sufficient. So Spud and I should be good to go as I probably have about 7 or 8mm of threaded engagement.

SpudRider
01-29-2016, 09:29 PM
Yes, I haven't had any problems whatsoever. :) However, I still might splurge for some custom spokes from Buchanans. Their custom spokes are very strong, and will certainly outlast the life of the motorcycle. :tup:

I'm switching my rear and front wheel to larger sizes. Rear 15 to 17in, and front 18 to 19in. I purchased the rims, but I don't know the length of the spokes. Did you, by any chance, measured the length of the rear spokes?

I'm unable to take the rear hub to the shop due to various logistic and physical location limitation. Really appreciate it if you have any information regarding the rear spokes length.

Thanks!

I used the rear spokes which were laced to my original rim. You can purchase these spokes from CSC, in Azusa, California. The rear wheel uses outer, and inner spokes. Both spokes are about 148 mm in length.

Thank you! :thanks:

I planned to order from CSC, but when I calculated the shipping from US, with the exchange rate not in my favor, the total cost exceeded the price for my new rear Mitas E07. :lmao:

Have you changed the front wheel to 19 inch? One of my countrymen changed his to 21, but he doesn't have social media, and we live on different islands. Still tracking him. :hmm:

Hi, I'm from Argentina and have also changed the rear rim from 15 to 17. The spokes you need are 150mm x 4mm.
As for the front, I already have the 19 rim but haven't had time to make the change. I measured the new spokes needed as 220mm (end to end) and they're 3.5mm. Be aware they the front spokes are "straight". When I do the front change I'll confirm spoke lengh...

Thank you Juanro! :thanks:

Now I can start hunting for the spokes.

I will certainly wait until you confirm the front spokes' size.

Bless you!

RonB, you can buy them here https://world.taobao.com/item/41535398030.htm?fromSite=main&spm=a312a.7700824.w4002-7242439086.70.IB6RIp for the rear wheel (size 15 inch). Still looking for the front wheel.

Hey guys.

After several months, I finally received my rear tyre.

I can confirm with 100% accuracy that we can use the stock 15inch spokes on new 17inch new rim. Thank you Juanro!

Now eagerly waiting for my 19" front E07.

I know I'm a little late joining this thread but I'm a new member. This is great information. I haven't purchased a RX3 yet but the first modification I would want to make is to change the rims. I hate black wheels on anything other than BBQ grills and lawnmowers (lol) so I'd want to change the rims to just plain aluminum.
