I see allot of new parts on these that I would be interested to get for my bike, including the alloy rims, but unfortunately I have a drum back brake and these are only disks.

Look how good the 250 looks now!

Yes, and weights extra 10 kilos. It's just engine.


A few years ago, at a time when "Qingqi's" 250 cc was new and rare, I read an article from some Russian motorcycle magazine. The first thing guy saw, is noticeably bulkier engine compared to the same bikes with 125 and 200 cc.

Disclaimer: I do not nag.

Prices of the Qingi 250 Liger in Columbia, by the way I think Mastiff is better name for these.

8,890,000.00 COP

I wrote earlier that I have read that the 250 cc bike weighs in excess of ten kilos compared to 200 cc version. Correction: extra 16 kilos.

"Силовой агрегат стал заметно шире и значительно тяжелее – почти на 16 кг!"

Yes, comparing differences
249cc to 199cc

Weight Dry Kg
142 -125=17
12% Increase

Engine Power Kw
15.4-11.5=3.9
25% Increase

Engine Torque N.m
19.5-14.5=5
26% Increase

I commented once before that as you increase engine size and weight there is a diminishing return.
There is less of a gain in the ratio for power to weight from a 199cc to 250cc compared to 125cc to 199cc as long as the increase in weight is under the increase in output the ratio is positive and increasing, but it increases at a decreasing rate with each level. To defeat this is the use of ceramics, water cooling and lighter metals, like titanium all coming with increased cost at production.

IMO, 4V head would be affordable way for improving power/weight ratio.

Speaking of 4V on "Suzuki" engine based clones, you recently mentioned QJ's GS clone with 4V. Do you have any additional information about them?

"Crossover" version of a QM 150 9R design - Turkish "Spada Anton" 150.

Unfortunately for Uniteks their website is not functioning. That is who is bringing these bikes to the market in Turkey. They are collectively importing and distributing for Indian, SYM, Victory and created a brand called Motoran that utilizes the typical Chinese multiple OEM business model.
