Does what it says on the tin

Doesn't fit my Triumph Tiger perfectly however good enough. Map case seems an odd size as it's close too but doesn't take A4 however a quick fold or cut sorts that. The quality is as you would expect from Givi and usual 1st class service from SBS

Perfect size & easy to fit

So easy to fit to the tank a 5 year old could do it. The bag is really easy to fit to the tank lock system too. A nice size, any bigger and you'll prob struggle to lean over it, not sure how you lean over a 30l bag. Comes with a rain cover.

Very Useful bag, but not perfect

Unlike some users I already had the flange for the tank lock bags as I had previously bought the 4 litre bag, but for holiday use we needed to raise our game, so I opted for this bag. It worked beautifully most of the time... Like a lot of other users I found the strap design a complete faff to use and debated about amputating it, but decided to persevere. For me personally the main irritant was the waterproof cover, not it's function because as a waterproof cover it worked perfectly in the rain we encountered, my biggest gripe was the colour of the thing.. in the wrong light conditions it bathed the screen of my sat nav in an eerie fluorescent green glow which made it almost impossible to see the detail on the sat nav display, my 4 litre bag has a black cover and causes no visibility issues, unlike the green item which really didn't help with navigating around the undergrowth in Slovenia... So apart from the strap and the cover it worked perfectly. Service from Sportsbikeshop was exemplary as usual...

Top bag!

Great tank bag as you would expect from Givi. Build quality is excellent and it's perfect for my Yamaha Tracer 900GT !

Very happy with this quality bag. Zips worked well, the protective cover kept the rain off. The locking system works well. There is not a lot of room between the front of the back and aux socket.

Don't forget your Flange

The bag itself is excellent and great quality. Just what I need for my next big trip on my new BMW GS R1200 Rallye (2018) around Europe. However, don't forget to order your flange separately. I ordered the bag from the SBS and couldn't work how to fit the bag to my bike. It was only after watching a YouTube video and doing some online research that I realised I had to order the flange separately. Makes sense now, however I didn't spot this was mentioned on the SBS website when I was ordering the bag, although it wasn't that obvious in my opinion. Nevertheless, great bag and SBS are still fantastic.

Good fit for a Triumph Speed Triple R

Good but not that good Decent quality tank bag but let down by poor quality zips. By the time it had been opened and closed a few times the zips would just burst open of their own accord, Too fine a tooth I guess. Everything else about it is excellent.

Fits a Triumph Street Triple R 2013 nicely!

Quality of bag is exceptional. Nice and rigid so keeps its shape. With the tank bag at its furthest forward, it's just enough so your not pressed against the rear of it. As it's quick release you can't really leave your bike with it attached, so I've wrapped a 6mm cable/coiled cable looped through the handlebars and a padlock through the metal loops on the zips to secure the bag if I have to leave the bike(handy also if you want to secure your helmet too. You can fit the waterproof cover in the side pocket so you have maximum usable space in the main compartment. Easily big enough for daily commute or a night away. Doesn't impede view of clocks or restrict handlebar movement left or right but it's the biggest bag you can get away with on the Street Triple R. The strap when looped around under the frame head stock has about 3" adjustment left. One downside to the size of the tank bag is it stops you leaning forward even a little, which is an annoyance if your sitting on your bike and want to push it forward. Very good value and quality is 10/10. Not sure if this is 15 litres expanded or 15 ltres not expanded? but it only expand upwards an inch so there's not much difference either way. When filling up with fuel I just unclip it and flip it over to rest on the clocks out the way. One thing to mention, the bolts supplied are quite cheap mild steel black plated bolts not stainless like the ones originally on my fuel filler flap.

Excellent piece of kit.

This tank bag ticks all the boxes for me, build quality,loads of space and especially the way it fixes to the bike with the tanklock system and most of all it looks good. SBS were fantastic again.

Just the job

Used this for my trip to the North West 200. It's just the right size for my camera gear, and a few other bits and bobs. And it all worked as it should. Using it again in a few weeks time for my trip to Norway.

Not for a Multistrada

Very nice tank bag, well made and well thought out but just too long to fit my Multistrada so had to return it. Shame as would have liked to have kept this for longer days out and touring. Recommended if it fits your bike however.

Luggage on my Triumph Street Triple.

I bought this system after reading good reviews of the product. I am not disappointed. Quality is good, and the system fits perfect and the bag is adjustable.

At first sight, looks a great bit of kit, well designed and made, a good size and doesn't look out of place when fitted. Time will tell after it has been used.

Tank lock tank bag

Very well made bit of kit which is easy to attach to the bike and subsequently remove. The tank bag feels very secure on the bike and if needed has straps to secure it further. Inside has a waterproof liner with two pockets at the side for phones etc. It also has a removal pocket for an iPad that you can attach to the top of the bag. I use this every day for work and has proved to be invaluable

Game changer!

Didn't like wearing a rucksack for work, firstly for safety concerns and secondly my rucksack wasn't waterproof. Got this to carry all my bits for work and it's the perfect size. I can get my lunch box, bottle of drink, work gloves, keys, sunglasses, hi viz vest and a few other small bits in there without extending it. Clips to the tank really well and takes the weight off your back. I did cut the strap off the front of the bag that's supposed to go round the headstock as there wasn't anywhere I could fit it on my bike and it just got in the way. Have ridden in torrential rain and the waterproof cover keeps the bag completely dry. Definitely recommended.

Excellent for the price

Does exactly what you want it to. Can't wait to get out on the roads with it, especially as going to Europe. Waterproofing a real must & everything about this, including the zips, says waterproof rather than water resistant.
