Expanding upon the previous post as I've said before to others about the Grom occasionally you buy a bike that just doesn't "do it" for you. Probably the worst was my '81 CX-500 that I hated from the moment I left the dealership but still ended up riding it 25,000 miles over the next couple of years simply because I couldn't sell the damned thing. Knowing what I know now I probably could have fixed it with careful carburetor jetting but as it was stock it took FOREVER to warm up enough to where you could actually ride it.
Another bike I never really cared for were the two CB-400F's I had in the mid-70's. After totaling one when a lady turned left in front of me after around 6,000 miles I foolishly got a second one and ended up riding it almost 23,000 miles. Considered a highly desirable collector bike today I thought it was a pile o' poop and back then once purchased you couldn't give them away (both of mine were sold new as leftovers). Now they bring stupid money as I scratch my head and wonder why.
In my 42+ years of riding there have been some real winners, too. My '84 KDX-200, purchased and set up from day one as a competition hillclimber, was a magic bike, gathered trophies like a magnet and continued to do so after I sold it. I got a case of sloppy sentimentality and bought it back to restore to how it looked during it's glory days but some scumbag managed to steal it before I could finish it. Bastards.
Another genuine winner was my '96 Gas-Gas Pampera. A cross between an enduro and trials bike it would go places you could barely walk and other bikes would have had to be air dropped into. Huge fun.
Honorable mentions--'99 ZRX-1100, '82 Suzuki GS-1100, '90 DR-650 and the NX-650/XR-650L's (three of 'em!) that I've ridden over 110,000 miles on. Too big and heavy to be a dirt bike but a more versatile street bike you'll never find.
So what excites me now? My fleet of junk step throughs powered by a variety of Chinese and Jap motors. An offshoot from my pit bike racing days I rediscovered how wonderfully simple these engines were and starting with Passport #1 (purchased on eBay for .99--no kidding!!) I've found myself riding them more than my "big" bikes lately.
If these ugly little bikes excite me so much why didn't the Grom do it for me? Part of it is the Luddite in me who fears technology. I've always had to do my own work (mostly because I couldn't afford to pay someone else) and despite reading and re-reading the shop manual I just don't grasp or understand fuel injection. I was a little disappointed in finding that the Grom ran no better than my Lifan 125 powered Passport despite it's whiz-bang electronic feeding system. I'd bet the farm there's more power to be had but having already been there, done that, bought the T-shirt with my stupid expensive XR-50 I ain't going down that path again and definitely not with something I don't understand.
Another thing is I'm so used to ugly bikes and ones with plastic tanks like my XR-L the Grom is just too pretty and fragile for my tastes. When you get old like me all of a sudden you have no one to impress but yourself and my bikes rarely get washed anymore, much less waxed and shined like the Grom seems to demand.
Maybe the Grom is the neatest thing since sliced bread. There's a lot of performance potential within the motor (the crank is well supported for one unlike the Honda 50/70/clones) but I ain't gonna be the one to discover it. I'm happy that small bikes are making a comeback with the Grom but it's simply not for me. Maybe it will be for you.
