Warning: looong post
since you touched sensitive subject
I have felt same when I had go on 05 Blade. It does not lack torque as long as you are in usable powerband, and you there beceause of gearing difference.
But. The main advantage of any big-bang bike, be it Storm or modified inline four (modified to run 2-2 big bang) is something else.
What I found after all "want-a-new-bike" tests I done
, and I stay by this statement: when you accelerate in corner, with bike leaned hard - where with i4 I had troubles keeping the line and grip and accelerating at same time
in the corner - with Storm I just drop into corner and wind it up while leaned. And I feel the moment when it is too much and it starts loosing rear. But most wonderful thing is - it just grips back on if you a bit back off throttle.
I had been given explanation on theory behind this behaviour. The man, who told me riding sports really fast, but since coupel of years his main "thing" is supermoto. And on his self-made XR based supermotard he manage to lose latest and greatest sprotbikes in twisties in France. It is proved - last time only guy on Speed Tripple suprisingly managed to hold on his tail while R1s and Blades just could not cope on anything less-than-perfect surface. He told me that his impression of Storm is almost like supermoto - come into corner as usual, drop it in, open up when leaned and fly out of the corner already on full gas.
So, what's all this about. If you sort suspension on Storm (good shock, good front) it can do wonders even with it's 100 bhp. With my bike if I do it within 5000-7500 rpms it's hell of fast bike in mountain passes, way more than I can handle. With my previous i4 I honestly was totally suprised when it had lost rear in corner in Alps. This is still my most terrifying memory in 8 years of riding decent bikes. And there was no warning, no way to regain control - nothing, just sit and wait to get killed.
Year later same happened to me at 50 kmph on straight road in rain - it just started to go sideways and going off/on throttle or anything else did not help - I wrestled it for good 30 meters and than wend sliding
With Storm unless you have diesel spill kind of thing it's pulsing power makes it feel like ABS on brakes and I am riding twice more enthusiastically and way faster in real life than I ever did on i4.
In previous trip to France in 7 days I never crossed 6500 rpm line because I did not need to and I never lost rest of group I was riding with.
Add to that fact that 160 quid can convert Storm in perfect tourer (second hand panniers/rack and spare rear plastic to cut, few days of cutting and welding + gel pad on pillion seat) and et voila 2-up tourer. convertible back to mono in 15 minutes. I am keeping mine
If not for homologation requirements I'd have built myself one like that but with front brakes and better seat and will be learning taking corners flattrack style
could only rev it to 8 thou as its still running in but still really fast made my storm feel slow but the best thing is the handling. This bike inspires confdents in the rider after just a few hundred yards and a few turns i felt at home on the bike and ready to push it further and harder into turns plus its so light and compact. If anybody is looking for a new litre sportsbike than i would recommend the blade
