Saving weight off you your gear or your bike is always a good thing. But its literally a balancing act between the weight and practicality and to some extent what you own or want to aspire too.
We live in affluent times, with many more than willing and able to purchase lighter alternatives to what they currently own and that's fine. But although there is no escaping the physical weight of any given item of the bike rider and gears overall weight, any given items position on the bike can make for a sweeter v handling set up or an absolute pig, its all down to how you load it and on/ in what as much as the accrual weight.
In view of this i avoid using hard cases or top boxes of any kind, anything to the rear or more importantly high and to the rear of any motorcycle effects the handling of the bike to variable amounts and of course dependent on the amount of weight / the bike etc.
I like carrying as much of the weight as possible in a 40ltr Tank bag, and any bulky light stuff i always strap to the pillion section of the seat, but even then i restrict my load in that area to a single British army patrol pack 99% of the time. I do have Wolf man saddle bags but i only used them a couple of times, preferring to travel light.
Regarding the Gear itself i run a mixture of old stuff i have had 40 years or more in some cases, and some newer stuff.
Cooking Stove, i have an ancient Radius Stove Its not as light as the modern lightweight offerings, and its Kerosene/ paraffin and needs A little meths to start it properly, but its otherwise faultless in over 40 years service and it was probably 40 years old when i bought it for 50P in 1972.
I also have a folding tin box stove that you run on debris and small twigs it works ok is light and packs small but the old radius blinds it for performance .
Cookware / cutlery
Mixture Of Mostly british and german army tins with Old household Knife fork and spoons i Attacked with a Hacksaw a bench grinder and a 6mm drill bit in about 1975 still use the same utensils to this day.
My cup i got off a scrap stainless flask in the early 80s its small light and perfect size for tea.
Cooking spacela i use cheapo wooden £1 shop ones i cut down so they fit in mess tins.
Bed use Bivi bag british army and Line it with my sheepskin i run on all my bike seats , and i dont skimp on sleeping bag, i use a eiderdown one which is 30 years old and not superlightweight, but its yet to leave me cold a single night even in heavy frosts. Nothing worse than even in summer waking up at 3AM when its breaking light because its colder than normal and you packed a lightweight bag. been there done that and i hate it.
Tents. Often use a flysheet only, took to this hunting in the bush in NZ an d it spilled over onto the bikes, and with a bivi and decent bag, its fine and i like fly sheets.
I do use tents and for years used a relum pearl ridge tent, but in the early 80 onward have had several dome tents and i have a blacks aquila i use occasionally but its no lightweight and we bought it for camping in the kit cars its a bit big for solo on the bike and if expect bad weather i might take it but more often than not use a fly if i can.
And to sum up. Packing light is good, but if you load the bike right saving every possible oz might not be nessasary, and remember if you dont have one of those it wont weigh anything, but skimping too much can make for a miserable experience sometimes. Its all a question of compromise and what you need or will accept.
