BMS Enduro 250: Counterbalanced or not
Hello all,
I searched, but did not find this answer: Is the SOHC CG250 in the BMS Enduro 250 counterbalanced or not? I think I read before it was not and I did not notice a bulge in the engine case. I am still debating if that is really a deciding factor too. I am leaning towards the Brozz 250, but I would like the taller seat/tires. This model has 19/21 tires. I did read about both the Northrider and wedooit reports. They seem to have had good results with this model. Thanks! tdk https://www.txpowersports.com/BMS-EN...-dirt-bike.htm |

It's interesting that Bashan has this on the same certification as the other Bashan bikes (this list is from the listing of bikes all approved: BROZZ 250, BSR 250, CR250, DK250, MOTOMAX 250, PRS 250, Razer 250, STORM 250--the BMS CRP is the CR250) but manages to use a different engine. Then again, so does the BSR 250, aka DB-250-41H (the one that looks nearly identical to the Hawk) which seems to use the same engine as the BMS bike. Interestingly, and I haven't corresponded with the N. American Bashan rep in months, but the last time I emailed he said that BMS was going to get their bike CARB certified as well for California (only the BMS bike even though its MCO and VIN# make it a Bashan bike). But, later on he said they had changed their mind; I am guessing dealing with their own state changed their mind!

If you look at the second photo in this thread, you will see the finned protrusion in the lower front of the crankcase. THAT is the counterbalance shaft. https://www.chinariders.net/showthread.php?t=28337

The page's tech specs say SOHC 4 stroke 4 valve. None of these cheap bikes have 4 valve heads, so that tells you all you need to know right there.
Also says 67mm/65mm bore and stroke and 229cc They took the information directly from the BMS website for this bike too. That's the sad part. The BMS web page also says 15.42hp. Pictures of the engine in the bike, the horsepower rating, the bore/stroke, and stated displacement scream it's a CG250, which is OHV not OHC.

No, it's not counterbalanced. I bought mine from TXPS. Quote:
Run of the mill CG250. The BMS website is inaccurate. |

BMS is it a really A SOHC 4valve engine?
Thank you for your information if the Engine were an OHC 4-valve I think they would be asking more than $1600 for it. All the other factory OHC 4Valves sell for over 2K.

We don't see OHC 4 valve Chinese bikes yet in North American market. They are OHC, but 2 valve. The Templars and Lifan KPX are good examples.

I would prefer no overhead cams, just pushrod. That way the engine has more torque, and able to go high speeds through extra tall gears. Or get a fully ohc, that way there's almost no torque, but good enough HP. But these hybrid engines, half pushrod, half overhead cam, are very inefficient. Not quite as fast as OHC, not quite as efficient as pushrod engines, lower MPG. Overall worse. |

But the 4V OHC engine is available in a 249cc ZS engine. One of our forum members has put it into a bike (photos!) Here is the engine. He bought it from AliExpress and as I recall, fabbed it into his grom clone. Now that was an upgrade! You can even get the 172FMM compatible head kit:
