I'm a scrawny runt.
I've always found shoving extra weight round the rear of the bike aids the stability of the bike given I've struggled with the rear skipping along dodgy roads. This now doesn't work as the load limit on the rack on my new bike is 3Kg.... AKA a large dump.
I know nothing about suspension.
Is there anything I should consider changing to help stop the kangaroo wannabe on my newish DR-Z400SM? It's nowhere near as bad as my previous bike but shoving a chain over the rear wheel isn't an option any more and I do rather like to have my set up feeling planted and ready for winter.
