Your call, individually drumstyx!The risk of a cracked tank, due to no crash bars doesn't seem worth the extra gallon to me.
Clarifying, TaiwanMotoGuy, you have a cracked KLR650 AFTERMARKET PLASTIC TANK?I'm with drumstyx on that one, I think. My current tank is cracked all to hell because someone dropped the bike several times in its previous life. I'm fixing to get some sort of quick-fix to make it ride-worthy until I have the chance to go home and get one of IMS 6.6 gallon tanks. I'd rather not rely on JB weld. Especially since they don't sell it here! I'd feel much safer if the crash bars would fit over the IMS 6.6 gallon, since I will be doing that "middle-of-nowhere" type riding and a cracked tank would suuuuck that far from a town or anyone that speaks decent English.
Experience dictates that the risk of cracking or damaging an IMS plastic tank is extremely low. In fact, after racing motorcycles with plastic tanks for 35 years (and hundreds of crashes) I've never cracked a tank.I bought my SW Motech bars from a guy that upgraded his tank.
I don't understand the 'tank provides adequate protection' argument -- These are plastic tanks and if they crack, you're out of fuel, and you're out a fuel tank, in the middle of nowhere, there goes your trip, period.

I have the 10.7 gallon IMS tank. I got it to eliminate the need for crash bars and the extra fuel range. I agree with Dave's comments on dents, rust, scratches and center of gravity. Mine is black (wish it was clear) and I have no problems with the stock fuel cap.....and the reason I run the 6.6 IMS has nothing to do with the extra fuel. I run it because;
- it protects the radiator without the use of crash bars saving 12lbs
- it is impervious to dents
- it doesn't rust
- no paint to scratch
- I like the ergonomics better
- it can hold the stock amount of fuel at a lower center of gravity
- I can check my fuel level from 20' away
- It allowed me to get rid of the problematic factory fuel cap.
Impressive. Obviously didn't protect the bike, but I guess it's fine itself eh. On top of my protection concerns, I also run a magnetic tank bag on most of my bikes, which is kinda no good on a plastic tank.I have the 10.7 gallon IMS tank.

I dropped it in a soybean field in Saskatchewan and found that the tank doesn't provide the protection I expected it would. The tank caved in and folded in on the left front and left rear corners like a plastic milk jug. When the front folded in it took out the radiator and when the rear folded in it pulled the fuel line and broke the inlet elbow off the carburetor.
The tank came out fine with no dents, cuts or leaks. I stood the bike up and watched the tank slowly regain it's original shape like a beach ball being aired up.
I am still running the tank. I put on longer more flexible fuel line and am adding a 1"x1" square tube across the front between the two forward lobes and bolted to the center frame tube to hold the lobes out and protect the radiator.
