Little More Power
on: July 22, 2020, 08:45:30 PM
Has anyone added a Power Commander or equivalent for a little more gusto?

There have been various threads about this topic.
In brief, yes - a few have tried the aftermarket fuel controller way. As there are no limitations or restrictions to overcome, these type of changes won't bring any reasonable power increase. The bike will probably act a bit more civilised between transitions of on and off the throttle, but no appreciatable power.
Having said that some peeps I know got over 40% improvement in terms of power, but the expenses are fairly more than a PCV for sure.
After all, this is only a 481cc twin.

To date, as far as I know, there are no plug in devices like a power commander that work on 19 model years onwards.
That could change overnight though.

Best way to get more power out of a CB500X is to trade it in on a bigger bike-I'm not trying to be funny It's just the facts-
It's not a big motorcycle just a groovy little motorbike

According to below link, riders from A2 regions are plagued with restricted velocity stacks in order to de-rate the bikes factory 37kw to A2's 35kw. This would explain why HP in the americas are usually given as 49.6 hp (50.4 cv in Brazil = 49.6hp) VS 46.9 for EU countries.

However, I've also read on this forum that all models are A2 worldwide ? Doesnt make sense though why Honda would derate an engine for all markets except A2 - power is a competetitive measure I'd suppose...  :084:

At any rate - looks like our A2 brothers can gain an extra 5.75% power by ordering a non A2 velocity stacks. I'd love to hear from any U.S / Canadian owners if they know for sure that they indeed have non restricted stacks in there.

P.S post is from July 2019 - not sure if this is for pre-2019 models - Honda did change the stacks for the 2019 upgrades. But question remains - are the 2019/20 models all the same worldwide unlike pre-2019 ?

changing the stacks on pre 2019 bikes has been done somewhere on this site-don't remember the out come-not sure how rwhp is figured to make a bike A2 because I have never seen a dyno measure more than about 45hp on any country-maybe it's done mathematically?

My ask is because my DL1000 had a fair amount but adding a PCFC 'loosed the Hounds' so to speak. The 500 test ride put me back to memories of my long gone KLR which was a little nerve wracking when trying to pass a semi. If a PCFC would give me that extra umph, I might invest.

So this may just be pre-2019 ? - in one of the written "reviews" for the 2019 model launch in Tenerife, last spring, a british motorjounalist commented on the 2019 delivering 37KW stock, but derated by changes to the "airbox" in order to comply with A2.

I guess my curiosity revolves around the 2019/20 models - Do we in the americas get the full 37KW ? - if not, then its reasonable to pursue an almost 6% bump in power by bringing bike back to its factory spec.

Anyone with any info ion this ?

Well i know that pre '19 have some restriction in the intake trumpets (about 20-30% blocked off) but for the 19 model the intake was changed. So i can't really say anything about the stacks on the new one.

I'm afraid not all, pre 2019 bike have the restriction my 2018 doesn't. Easy enough to check though, if I remember rightly it was the earlier models that had this.. Haven't read about this with later models, maybe someone needs to have a look at there stacks
