I just bought a Kazuma "Dingo" 150 and according to my handheld GPS, I can get it to a top speed of 29 MPH. My Kazuma 110 (MKI, the old version) would do 33 MPH. So the 150 is 4 MPH slower than the 110. I ain't happy about that!!!

Plus, it sound like the motor is screaming just to get that 29 MPH.

I'm thinking about having some sprockets made for it.

Does anyone know if there is a cross reference for a front sprocket? In other words, is there a ATV or bike on the market that uses the same front sprocket? That way I could just order one.

Thanks

 

For a sprocket you my want to try these guys!

I did call them earlier and they said they could make sprockets for it no problem as long as I send them the originals. I was looking at the front sprocket and it looks like a Honda sprocket to me. I'm going to see if I can cross it with a Honda sprocket. Trial and error I suppose.

Here's some good info I did learn today that I would like to share that maybe you can pass to your customers. I spoke to a gentleman at Kazuma Pacific today and he said they have 23, 26 and 32 tooth rear sprokets for the 150's. For comparison, I think the stock rear sprocket is a 30 tooth. They take the parts orders online only at www.kazuma-us.com. I think the sprockets are something like $22.00.

The 26 tooth sprocket would give me a 14% increase in speed or 4 MPH. The 23 tooth would give me a 24% increase in speed or 7 MPH. That would still only get me up to 36 MPH which is still pretty lame. I question if the 150 motor and CVT transmission can pull that high of a gear from a start and not cause excessive wear and tear.

If anyone else has and more suggestions for getting more top speed....I'm all ears.

 

I hate to be the one to say it but here it goes. I Told you so. The only reason the dingo goes as fast as it does is because of the 22 inch tires. The rfx only has 19 inch tires. Do the math, even slower yet. I have a dingo also, except I believe it is called a KMX 150, same thing, different sales pitch. Good luck with it, we use ours now for hauling around lawn carts and stuff. Too slow to actually go riding with and good luck trying to sell it for what you paid for it. Everybody around me has them for sale, every little pawn shop and mower shop. Just try to have some fun with it, you own it now. Also on the front sprocket situation I do not believe that there is physically enough room to increase the sprocket size and going any smaller on the rear would just beat the crap out of those already flimsy tensioners and probably eat through the swingarm, but please keep me posted I am still looking to make mine faster as well, but I pretty much just gave up on it and will throw it away when it dies.

 

Yepper.....you did send out the warning. Too bad I found this forum after I bought it.

There is plenty of room for a larger front sprocket. There is 1" or more clearance all the way around the spocket and if there is a problem, I would just do without the guard. I could swear that it's the same sprocket that a Honda XR 100 uses.

I'll keep you posted.

 

That would be great if it does work but do you think they make a 15 or 16 tooth front sprocket for one of those? The stock Kazuma one is 14 already. Also you probably know this, but after about 2-3 hours of riding my motor came very loose.It only has 2 bolts holding it on and it caused the intake rubber to break from the vibration I guess. This thing is made very poorly. You get what you pay for. However they are a good starter bike for young kids. I replaced the rear shock (because they are only a spring on a pole and not an actual shock) with a suzuki lt 230 front shock with a little modification of course and it made a big difference. And if no one believes me about them not being a shock take one apart, it is very easy to do. They offer NO dampening at all. The lady I swapped my rfx for kmx to said that she has had a ton of them come back for gearboxes as well. She was however able to get me a new intake and it only took 2 months. Overall they look good and sound fast but they are more like a power wheels than an atv.

 

Yeah....I agree they ain't a work of art....that's for sure. No, I didn't see about your motor coming loose. I'll be on the lookout for that.

I doubt they do make a 15 or 16 tooth sprocket. I may be way too optimistic about that.

I see these advertised in many places that they do 47 MPH. I see plenty of 40 MPH quotes as well. Isn't this false advertising?

 

I definitely believe it is false advertising. I contacted an attorney about it and they basically told me that I was out of gas because Stanic manufacturing is based in china and it would be nearly impossible to fight them out of the country. The guy I bought them from offered me a refund but I had to pay the 4oo.oo return shipping charges so I said screw that. I dont understand it at all, that it why I started posting on this forum, to protect others from the same mistake. The guy Sonny (Kazuma tech support in china) said that there is no way these things would ever go 40 mph. I posted his statement in another forum. I have been met with criticism from some about this but none have the same bikes to argue with. I posted the facts as I found them out. I bought 3 of these at one time, imagine my displeasure. And this was after speaking to the guy selling them 3 times prior to purchase telling me how fast they were. Then after I contacted him he told me that he had never actually had one of these models. (Dropshippers, thats all). If I am not mistaking even the raceway atv guy John said in a prior post argument with me that his go 40 to 55mph...HMMMMMMM.... I wonder? How is that possible when nobody elses do?? Must be that Kazuma rocket fuel that doesnt come with the bikes.

 

Thanks Turbomike for the info.

I have mine up for sale. I sold my Falcon 110 MkI fairly fast so I could buy this one. Maybe this one will sell also. I currently have it list on the same website. We'll see what happens. Too bad, because I really like it except the speed issue. I haven't (yet) had any other issues with it. My shocks are actually pretty nice. They dampen the rebound and work the way they should.

Are there any other options out there for a Chinese ATV that will actually go 40+ MPH?

 

I have no idea. I am staying away from the chinese stuff. For such a little bit more money you can go with a name brand. Honda was running a special on 250 ranchers for 2500 last timeI was in there and I know that the suzuki ozarks are right around the same or less. Good luck with it whatever you choose.
