I havent had any experience with these particular ones but I have used adjustables similar to it on all my bikes including my 1200.
JMHO but as risers I dont think 70mm will be much higher than the OEM ones. That is assuming that it is a 70mm rise from standard clip on height. The stockers are somewhere between 2.5 to 3" above a standard clip height to start with.
If you are looking for just a 3" riser then you might want to also check out the Apex bars http://www.apexmfg.c...x-riser-clip-on. They are a really nice bar for 219.00. But if you are going up from stock height then I dont think 3" will help much.
The cats meow for adjustability are the convertibars by far IMHO http://www.convertibars.com/. Those things will go up like 8" if you want to go that high. I think they were around 260.00
Keep in mind I use mine to get the bars lower than stock. But it gives an idea how they look on the bike. The german ones look quality but for 319eu msrp I just think there are better options out there. Once again JMHO.
