Anyone know anything about these? I've found a little info on them but just curious if anyone here has one or has seen them in their area. I know a few people have bought them but noone has had them long enough to tell. I could buy one for around $800 right now. Don't worry i'm not, but i did get the offer. Just curious now. That seems really cheap for anything that could be even descent.

Well like i said a local shop has been pushing these things like crazy in my area. They talked my dad into buying one last night. If you go to our local big bike track these things are everywhere now. They are so cheap.

I'm giving a little review since i rode it last night for a couple hours. My bike is a actual Honda CRF so i'm really curious to see if this thing holds up.



My review



My dad paid $800 for the bike.

Image




This first thing i noticed was that the bike was huge compared to mine. It comes with 12 inch rims and a 125cc JIALIN (made in China). It looked really nice IMO. Didn't looked strange like other packaged pitbikes i've seen. This bike has a electric start (which we took off) but it will start in any gear with the clutch pulled in.



The bike sounds really nice and has some very smooth power. The biggest suprise was the gear box. It was actually smooth as silk. The bike comes with a 4 speed manual. The suspension setup was really nice for my wieght (165 lbs) and the disk brakes felt really nice. (I wish i had those on my bike.)





On the downside i felt like the bike was really heavy. Even with the battary removed it didn't feel like a good balanced bike. The clutch was anouther downside. It was so stiff it almost hurt my hand to pull in. I think it will loosen up a bit but it will always be stiff. Anouther big complaint was that it was impossible to find nuetral. I'm serious when i say i never once got it in nuetral while the bike was running. When the engine is off it was easy to shift into second and just tap down into nuetral. The last thing is the kick starter seemed to stick out farther than my CRF. I have caught my pants many times on my CRF but this thing it touching my leg all the time. Its really in the way.



This bike really suprised me. The only other package bike i can compare it to is the xtreme. Thats the only other bike i have rode and seen the quality. I would say this is as good if not better but the price is half. Now the bike only has about 3 hours on it so now only time will tell if it holds up.





A few specs:

estimated 12hp 125cc engine (i think its more like 9hp)

9:5 to 1 compression

12 inch wheels

disc brakes front and back.

Very beefy front forks

nice heavy duty swing arm.

154 lbs

I have a boreem 125,first change the oil put a good simi sythetic in it.take the chain tensioner off and put a sikk chain guide on it 40.00$ the bike will shift and now go into nuetral .



2)Take the clutch cable bracket off the motor and mount it to the frame on the motor mount web(you have to drill a hole) so that the cable is now pulling straight up(its now out of the way if you want to put a after market pipe on it) and run the cable along the back bone.You wont believe how easy it pulls now.



3) Put a set of sikk bars on it 40.00 the stock ones suck!



4)put some kendas on it 45.00$ Make sure you check the spokes before you ride it.I didnt ride mine with the stock shock I put a Ishock on it that I had.Ive ridden mine for about 6 hours at elsinore and ive tryed to be has hard on it as I could and I havent broken anything yet.

For the 950.00 bucks ive got into mine I think its the most bang for your buck

Dude I think you are on drugs. There is no way this engine makes 9 horsepower. Have you ever ridden a true 9 horsepower bike? You would be lucky if it is pushing 7. It is getting so rediculous how these companies are inflating the horsepower numbers.



My neighbor just got a new bike, and was told it had 10 horsepower 125cc. I have the TBolt 125 which dynos no where near that, and I kick his ass everytime we drag race. I know my engine is not making anywhere near 10 horespower with an inner rotor kit, pipe, and 24mm carb. I think my neighbors bike is only pushing about 6.5 horse. But like you he is convinced it is so much more.

Nope sorry no drugs here, i was just guessing. The only bike i have it to compare to is mine which is probably about 5hp maybey (once again guessing) and it felt about twice as quick so like i said i guessed. They honestly say they make 12hp, but i know there is no way.

where did he buy it from? (question about the BMS bike)



and mike, thats how it is with all these people selling these chinese motors.....they try to convince you that since its cc's r so high that it HAS TO smoke the other motors out there......and thats what pisses me off most about these people selling these chinese motors.......its one thing to sell somethign as it is and tell them the truth about it but to go out and make false specifications of the motor and claim it is super fast high hp motor is a joke.



you know as you bought a 125cc motor that i bet my 88 puts down the same power if not more on a dyno......regardless of money spent into the two its the fact of the matter.....



im not saying its junk im just saying watch out for these companies who lie about their motors......or "hide" the truth.......and we got a couple paid advertisers here just like that....no names given of course. but just watch out what you get sucked into buying......these motors arent cheap......and its YOUR paychecks..... ;)

My dad got it at a local bike shop here in Oklahoma. BTW i would never buy one of these. I'm a honda man through and through. I bought my stock crf in 04 for $1200 and have put about $2200 in it and i haven't rode a bike i like better. The extra money is well worth it. Here in oklahoma the xtreme 107cc and 124cc are popular and its funny how many people have broke bikes when its time to ride. I'm in the casting industry and i know how China does their casting and they are crap compared to japan. Cost is low but its still crap. :D

Boreem is the make (like honda) bms is the model.I rode a 88 with a super head and then mine and I think the 125 pulls beter off the bottom but the 88 pulled a litle beter on top. The 125 felt lazy compared to the 88, but the 88 has a lot more compression so that could explane it.I just took all the electric start B.S. off it and it took about a pound off the crank,plus i,m having the head milled a little bit .So i'll see when I get it back together.

Well after the weekend of riding i've decided that the bars suck a big one. They are so soft that you actually crush the bars in the clamp if you get them tight enought to not move. The bike seems to have some slight rattles already (not sure were yet) and the tranny seems to be very tricky to shift. I'm putting a semi-syth oil in tonight so i hope that helps. Forks looked good but seem to rebound different over every bump. Nothings really broke so far but it already feels more ragged out than my crf that i've abused for 2 years.

well . .

my uncle sells these bikes and id have to say there good for about 5 rides and then after that they start deterating. such as the plastic side panels are made of a hard plastic that breaks by a touch of your leg while riding, second the clamps are to big for the standerd 7/8th bar so no matter how hard you tighten it, it will still move on you. third, the shocks re-bound goes out quick on them.fourth the air filetrs glue melts off and the foot peg springs are so weak that they rattle up while reving the bike. so with this stuff as a facter i would not waste my money on them. by the way bms 50s are pretty stocked on the number 36 hahaha

The foot peg springs suck!!!!! The foot peg actually flipped up on a jump when i lifted my foot of the peg and i missed it on the way down and jammed my leg into the ground pretty good. Those need to be replaced ASAP!!!

The gas tank broke last night. I guess the gas cap was a bit to tight and when it was taken off it actaully broke around the threads. It looks like tank is molded together from two peices (guessing) and they split apart from a little bit of torque. I'm glad this bike isn't mine. You get what you pay for most of the time....... :wink:

I dynoed my brothers yesterday it made 7.2 hp and a stock crf50 made 1.2



I bent my frame,but it took some good size jumps to do it.The air filter came unglued.My springs on my pegs are getting lose also

The local bike shop welded some frame supports on last week because they were having some issues with some frames bending. They fixed the gas tank but the cap just doesn't thread right (really tight). I used a stock honda cap and it went on perfect and sealed nicely. Its just going to take while to work out the little problems it has but this bike won't get rode hard by my dad so it might hold up.
