Optimum RPM to change gears on a Honda CBR 250R?

and

(Engine power in KW / Dry weight + 90Kg) x 1000 = Kw per tonne.
Motorcycles that meet this criteria must be under 660cc and have a ratio of 150Kw or less per tonne.

bummer. According to my calculations it works out being 162kw/t. Can you get a dyno check done to see if its lost any power? is the KW at the wheel or the crank?

I have just put it through NZ compliance and it passed easily so will come with a brand new WOF.

the guy said it only needs a plate and rego and then it'll be fully legal

[DrunkenMistake]

According to the Aus Lams, which our new rules will be exactly the same,
the VFR and RFV 400's are both legal.

and yah I seen that after, sorry

ok sweet as, im checking it out at 7 tonight with the cash. Is there anything i should look out for other than the usual (chain, sprockets, oil, forks, brake pads, discs, coolant etc..)?

thats yours? i saw that when i was hunting for my mc19... I wouldve bought it off you if you didnt live in Dunedin. Nice pics and bike - you should keep it.


..this thread is turning into a msn convo, i think a mod will move it soon.

"General Bike Ravings"
this seems pretty General to me, and its all on the bike mentioned in the topic? haha,
check the sprocket at the rear, see if its worn down, tyre tread, look for any scars on the inside of the fairings as it will indicate a drop, otherwise i cant think of anything else, make sure it runs haha.

sure will


have you worked out your fuel consumption in kp/L for your 400? im not sure if I should sell the MC19 or keep it for commuting and just have the vfr for playing round (in winter ). My mc19 gets a consistent 23-25kp/L no matter how i ride it.

[DrunkenMistake]

I honestly have no Idea ae, I think I could get 150km before I hit reserve, and its my general commute (when I upload this vid from this morning you will see the road I take, and understand why I chew the gas)

Open Road I would say an easy 250.

Where did you get the 90kg from? does that represent the "riders" weight?

Just uploaded it,
and its on that site.

Sorry to hear that, you could always get 6inch heels attached to your boots . I only just realised how amazing the vfr400 looks - it was love at first sight . I think im gonna have to get this one. I called up the guy and he said he'll take 3k. The K's have probably been wound back or something but as long as it holds its value i dont mind. That will be awesome when it becomes learner legal $$$$$$... Since theres no plate for me to carjam ($270ish for a plate and 6months rego apparently), is there any way to check if its been stolen?

That bike is a pos, stay away from it. One of the worst NC30's i've seen for a while and the guy is just clueless. Running horribly lean at idle with a terrible tin fart exhaust, rust infested tank and pitting all over the fork legs. K's don't mean jack shit I tell you, it's all about condition with these older bikes. I would have to think hard about taking it for 2g. No doubt some sucker will fall for the 'low kms' though and face many headaches, alas.

Mileage is good on these bikes... on a constant sub 100kph cruise, I can get 3.3l/100km or 30k/l if you do it that way. Again it's all about how you ride it so constant cruise is really the only reliable way to measure.

Oh and Drunkn Mistake- pretty sure VFR400 won't be learner legal... only the RVF400 NC35 will, right?

me vs westy on his MC19 - he kept having clutch problems though

He was warned

thats an awesome road. Nice riding - bummer about all the cars. I think once i get out of debt ill invest in a goPro


this was listed on trademe about 20 mins ago. What do you think? Lowest price is 3.2k without gear. he said he "rebuilt the front forks so they are mint, no fluid leaks, no rust damage".

So long as its sold with new wof and Rego i couldnt see why not. The rebuild of the forks is common, its a 20 year old bike, and by rebuild he probably means replaced the fork seals and oil. thats regular maintenance.

Its not that much to get it bike tranzed to you,
ask if it comes with the stock front cowl.
