center stand

pyoungbl · 02-02-2023, 11:26 AM

If you look at the RX4 frame you will see that there are no good mounting points for a center stand. On the RX3 it is possible to mount a center stand using lugs which are present from the factory...they were used during assembly of the bike. The RX4 does not have those lugs...because there are no frame rails under the engine. The bash plate mounts directly to the engine block for the same reason.

As for the battery, we all know that Zongshen cut corners to keep the price down. That's not unique to Zong, lots of other low cost bikes have the same 'feature'. The same goes for the suspension bits and the chain (although I think the chains are now much better than the early RX3 models). Since there is a constant parasitic drain on the battery it's unrealistic to think the battery will retain a charge for months at a time.

Finally, my TT250 had a kick starter and that sure was handy. It helped that the compression ratio was only 8.7:1 so I could spin it pretty easily to start even when dead cold. The RX4, on the other hand, has a CR of 11.0:1. Even with the automatic compression release I think I'd be hard pressed to spin that lump fast enough to fire. Even if I could do so, the fuel pump needs electrons to work so my efforts would be wasted.

From what/where is this parasitic drain being generated?
I guess I was lucky, never had a problem with its battery, yet (still using stock battery: RX4 2019-20). I will be getting a NOCO soon though.

The clock is constantly draining a tiny amount of current from the battery. The ECU is probably sucking a few electrons too, just to maintain settings. My '21 RX4 is still running the OEM battery and I intend to replace it soon, not sure i want to go the Lithium route. A good friend had his whole shop (motorcycle dealership) destroyed when a Lithium battery caught fire.

Peter,
That's a very legitimate concern, tell us more?

The Noco, like CSC, deserves a fair shake though.
The packaging is grade A+ imho, instructions too, and the battery itself exudes quality.

I have not used the smart genius charger I got from them, but I can say both my RX3 and RX4 crank/start instantly now.

Your choice of course, but thought I'd share the links.

What I know is that my friend took a bike into his shop for service. The owner had installed a Lithium battery. While the shop was closed for a long weekend (Labor Day?) the shop caught on fire. Said fire was traced back to that particular bike. As an aside, the when the battery caught on fire it produced fumes which permeated the shop and cause oxidation and rust throughout the shop. All metal tools were ruined. All the bikes in the shop suffered from oxidation to the point where most were a total loss. The actual fire damage was far less than what was caused by the lithium battery fumes. Later my friend talked to some other shop owners who had experienced similar losses due to lithium batteries. Law suits followed.
