Hey guys dis you realize the fact that the dynamics of the engines of cbr250 and cbr500 are nearly the same?
both has peak hp at 8500 rpm and peak torque at 7000 rpm just they cut the engine on 8800 - 9000 rpm on cbr500 i am sure for fuel economy as it is going until 10,500 rpm on cbr250 but run out of the steam of course after 8500 rpm.
Compression is the same too: 10.7:1
It looks like they have just glued two cbr250 engine together, not much. I am sure most of the internals are the same as well possibly a bigger counterbalancer though.
And most important and interesting fact at all: Their WTMC fuel consumption figures are the same 27 km/liter, think about it, a a 500 c engine giving the same fuel consumption figures as a 250 cc!!!.
That is great job IMO for Honda if it is true. Well done really, getting the same fuel economy like cbr250 on this 500 cc is totally amazing man!!!
By the way, the full engine specs: 47 crank hp at 8500 rpm and 44 nm torque at 7000 rpm. This site explains everything spec wise.: http://www.hondamc2013.com/bikes/cbr500r/
but is this an international site or just connected to the UK Honda site?
Hope we get a bump on it for Thailand though for power, please Honda
Note: And also, cbr500 has two 55 w bulbs and cbx and cbf has one and it is stated as 194 kg with ABS which is pretty OK! as i was expecting 4 kg on top of 194 for ABS version.
By the way the information on weight changes everyday nearly man. In USA Honda site, it was claimed as 430 pounds and now it is 425 wtf?
