I received a bonus from work & am looking to upgrade.



I'm not sure yet if I am going to keep my 1997 KDX200 in the shed, or if I will sell her & put money toward an even later model bike.
I have green blood running through my veins, so wondered what peoples thoughts were for upgrading under the big K banner????
I'm looking at mainly single track use with the odd rough old country town mx track as a treat. I want excellent suspension, but I am old now & ride alot slower than I used to. I am looking for a bike to build my skill, nerve & strength on to charge fairly hard for an old bloke.
The KDX is my first bush bike for about 18 years. I'm a fit (ish) 44yo @ 95kg or roughly 190lb.
Is the KLX450 a decent bush bike? Would a KX450F with a headlight be a better option? I probably wouldn't notice much difference in gearing...
Is here plenty of smooth grunt from a KX250F for my size nowadays? KLX300? I dunno - What are peoples thoughts???
