Revolutions At Cruising Speeds

Sorry if this has already been covered I searched but got no good results

Now I did  a 450 km trip (in the pouring rain and loved every minute of it ) yesterday and I seemed to always be reaching for another gear when sitting on 120 km/h Speedo reading (113 km/h GPS speed)  now this equates to 5000 rpm on my 2004 6th gen

I have a 43 tooth rear sprocket but I haven't had the front sprocket cover off to count the front teeth yet

does this seem to be inline with what others are seeing in regards to speed /revolutions ?

My mods are a pc3 usb and a set of 2Bros pipes and the bike seems to have plenty of pull but could possibly  use a slightly longer set of legs

Cheers

James

My stock 6th gen is identical to yours. Personally, I think the gearing is tall enough as is and the engine is quite happy, smooth and very efficient between 5000 and 6000 for highway cruising.

I find 6th gear below VTEC to be a bit on the sluggish side and taller gearing would certainly make it worse.

I went +2 on the rear sprocket and wouldn't go back.  After a lot of time humming and hawing over what it would it would be like I made this chart with all the popular gearing changes to look over while I considered what to go with.  You may find it of some use as well....

If the bike had longer legs I can only imagine the trouble I'd get into - 6,000 rpm in sixth has me around 135km/h (84 mph) and that's plenty for me.

Thanks for the replies guys

Just wondering what others were reving at due to the need to start looking at new chains and sprockets in the near future and this would be as good a time as any to change the gearing  if needed as the open road limit here is mostly 110km/h and everyone does 120-130 km/h

My bike is far from sluggish in 6th below 6000rpm it is like a great dane pulling on the leash from around 4000rpm in 6th and just wants to run and is still very tractable from as low as 3000 rpm's and has been since I installed the pc3 with cozey's map with a few tweaks and the 2 Bros pipes 

and I get 18.6 avg km's liter on longer trips with quite a bit less when hammering it in the tight stuff

I am probably jaded a bit because I had a first generation FZ1 and a 919 before the VFR and those both had big juicy gobs of torque available while cruising in top gear.

For reference, I seem to average around 19-20 km/L on longer trips.

I hear ya on the liter bikes as I have been road riding for over 30 years now and have had Blades , blackbirds,vtr's  gsxr1100's etc etc

But I like a bike you can actually use on the road not just tickle the throttle like the bigger bikes forshort periods

And sometimes less is more andthe VFR is definitely a cas of being greater than the sum of it's parts and surprises quite a few bigger bikes unless the road is boringly straight

As we know any IDIOT  can go fast in a straight line  he he

Couldn't agree more and that's what I love about the VFR :)
