They're apparently pretty nice bikes. Seen a few YouTube reviews on the 300 already.
Curious at the 0-100km/h time, it seems a bit honest; the Ninja 300 has slightly less power but clocks a quicker time, if I recall. I wonder why a bike of similar weight and power (a couple more horses) is a little slower; geared longer, perhaps. It has pretty big tyres for its size. |

i dont get how they get 38 hp out of the little inline twin 300, but we can only get about 15 out of a 200-250cc single.... wheres the massive power loss? is there taht much room for improvement on the small cg and cb???

Liquid cooled, higher compression, OHC,4 valves per cylinder, Red lines @ about 12,000 rpm.

CG and CB motors will never make that kind of power. 2-valve pushrod motor is a completely different class. Even the Virago V-twin motor only pushes out 19hp out of a 250cc twin. It's a 2-valve-per-cylinder single overhead cam aircooled motor.
Going 4-valve heads is a way to get more power. Tighter tolerances and higher compression is a way to get more power. But this generally requires water cooling. Spinning the motor faster is a way to get more power. But pushrods can't go that fast, so overhead cams are required. Timing the exhaust and intake valves more precisely is a way to get more power. And that means independent intake and exhaust cams. All of this adds up to make a far more complex motor than the CG mill. But also a far more powerful motor. And modern machining and metallurgy allows it to still be completely reliable. Charles. |

Yes, sure, you can build a pushrod motor that can go faster. You build out the other areas to their maximum, and take the hit on RPM. But all things being equal, if you went OHC of some sort you'd be able to spin that same motor faster and make more power.
Pushrods just have too much mass to allow the engine to spin fast. Unless you can make them really, really short, you're looking at 7000-8000 rpm, max. The TNT300 redlines at 13,000 rpm. Charles. |

![]() using that power to displacement number, a cg200 should theoretically be able to make 28hp, and a 250 theoretically could make 35... wouldnt that be nice..LOL anyone got any ties to nascar engine builders? see what they could come up with for a china bike...LOL ![]() |
