the fmx 650 isa supermoto style bike , basically a slr 650 which is a dominator without fairing not a bad bike , reliable ,looks good , and rides well but the engine is unchanged since the 80`s of the last century
also the frames are i think nearly the same since the 80`s so a bike thats in production since
nearly 30 years , only downside originally the engine had i think a poweroutput of 50bhp
but already in the slr these 50bhp came down to 44 bhp then to 39bhp and in the fmx there are now
just 37bhp left , not realy competitive in the supermoto leaque in thew 600+cc class
where the fmx has to compete against bikes like bmw g650 ( 53bhp), ccm r30 (50bhp) ,
husaberg 650e (63bhp),husquarna sm610 (53bhp) ktm 690 supermoto (63bhp) mz baghira supermoto (50bhp) and the yamaha xt 660 with 44 bhp) so in a ideal world the fmx is a good choise if you want something bulletproof , but the customers think of it what it realy is, a dated old hack with some new plastic parts , so the only chance to sell a few are to drop the price dramatically what honda did , its the cheapest , but if you want a bike thats reliable , and if you dont care about
that the engine is a bit dated and underpowered compared with the other supermotos , for everyday use you wont find a better bike for that price in the 650cc class if you look for a thumper
in the real world you dont realy need more power , and with a little fiddling (in germany is a company they have specialised in thumpertuning and give the fmx what she deserves (697cc and 59bhp)
