Just browsing Ebay as you do and spotted the Givi system tank bags with the clip on the fuel cap. Theres the XS 306 which is 25 litres and XS 307 at 15 litres. Anyone use one? My friend has the DP 10 litre bag and said it was tiny so was probably thinking 25 litre I guess.... Am thinking of the TT trip next year.....
Had a good look at the Givi offerings at the NEC today, the fitting system is genius. I am looking at the smallest in the range 4L, as I only want it for odds and sods. A word of warning though Givi are releasing some new models early next year that incorparate a USB charging system that can charge up to 4 devices. If this is of interest to you I woud hold out.
Also check the Bags Connection offering. Had a small tank bag for many years and it's been great. Not cheap but good quality. Bags Connection Motorcycle Tank Bags | Tank Bags
Update..... They aren't actually new models, there is an add on usb power kit which is coming around end of Jan beginning of Feb. I have just bought the 3D603 and will be getting the power kit as soon as released.. The best price I found was at bykebitz but they were out of stock, ghost bikes matched it though and I got the bag and fitting kit for £89 delivered.
Hmm they do a 3D604 which is 15 litre. Wondering if that is big enough. The 25litre one may be a bit too big....
Depends what you want it for matey. I got the 4L version, it holds my keys, wallet, phone, earplugs, shades, neck warmer, gloves and still has space for more. The 3D604 to me looked a little odd, out of proportion even! The XS307 looked pretty neat but too big for me personally.
