I've made the exact same transition about 6 weeks ago. Don't regret it, for a second.
To clarify, I put in about 100,000 Km on my 09 model (purchased in April 2010), With a good combination of long rides, (in excess of 12,000 Km), long day rides, ( 500 Km) with most of my riding between 200 to 300 Km on a weekend day.
I had the machine serviced pretty much as on the recommended schedule, but probably skipped out on a couple of the Valve Clearance adjustments, but mostly it was on the prescribed. intervals.
As far as the original bike performance goes, i really only had 2 failures. the first was the Alternator stator at about 52,000 Km just prior to the expiry of the 2 year warranty time so the stator and the battery were replaced under warranty.
The second failure was the water pump which failed at about 94,000 Km, a few days after I had returned from a 5,000 Km, 7 Day ride through outback Queensland.
Apart from these two instances The bike has served me well and given me an enormous amount of enjoyment and satisfaction. In short, It has done me well but i could see problems and expenses looming in the future.
HOWEVER, because of my preference for long solo rides in remote areas I started to think about reliability and "What is the next thing to give me trouble" and will it leave me stranded somewhere. In the back of my mind there was the notion that Alternator stator winding was probably close to failing again, (given it only lasted 52K the first time).
Without really planning to I saw the new model, and tok a look over it, Organised a test ride, and actually liked the lighter machine weight and the narrower body. I was hooked and signed the contract.
In the new model i saw a lot of the modern innovations that I was originally wanting in the 09 Model, but didn't have, even thou I decided to take it anyway, namely ABS, Traction Control, Remotely adjustable Suspension, LED Lighting, Self cancelling Indicators, and other little niceties in the Display area. The heated handgrips are a nice touch.
Handling wise, I think you can really notice the 10Kg less weight, and the handling is as surefooted as we expect of the VFR. The transition into "VTEC" is different. The jury is still out on weather it is better or worse. If you take it relatively easy the transition is very smooth, however if you have a handful of throttle , the transition hits with a bit of a thump, not dangerous but enough to make me think, "is there something wrong here?"
I've been travelling overseas for a few weeks since then so i have only just completed 1,300Km. The first service completed and Factory Panniers and top box are fitted, so I am now planning a longer ride to try it all out.
I apologise for rambling on, but I just wanted to give you some background on the type of riding I do, as I know each of us has different riding preferences and as many different ideas of "Perfect days" as there are people you ask.
Hope this helps
