EK ThreeD Chain 525 Z Series X’Ring Chain – GOLD, CHROME or BLACK (140 link length)

Product Description


As soon on our own 2020 BMW S1000RR, this stock replacement chain will you to extend the wheelbase of your stock S1000RR.  Extending the wheelbase is a must for people looking to drag race.  The further back the rear tire is, the harder the motorcycle is to wheelie.  The more power you can put down without lifting the front tire, the faster you’ll go.

The stock wheelbase of the 2020+ BMW S1000RR is 56.7 inches.  This modification opens the wheelbase up to 58.25 inches.  You may think the results would be insignificant but it really changes how well the motorcycle can put the power down without lifting the front tire.  The stock chain is not long enough to move the tire all the way to the end of the swing arm adjustment.  This is why we changed over to a EK Three-D Chain.  We still have stock sprockets on the motorcycle.  The only thing you will need to change for this modification is the chain itself.   If you are aiming to do what we did to our motorcycle, please also purchase our front strap kit (AVAILABLE HERE) and a lowering link for the rear that will be available soon once we have more testing time.  This will maximize your results.  This chain will need to be shortened a few links and we recommend professional installation.

See this product in action here: (please note, our 2020 is also lowered as well as stretched)

  • “ Bike is running awesome and no out of the ordinary popping under load during downshifts at high rpm. My hats off to your team for making me feel like I have a personal tuner at my disposal. Really appreciate the quick turnaround to get me straight. I can definitely feel the extra power! ”

  • “ This product is amazing.  I feel like I have a better version of my bike.  Like it should have come this way.  The throttle smoothness and even power band make it a joy to ride.  I no longer feel as if I'm riding a wild bronco lol. Thank you again, I didn't think that a L-twin could behave this well.  Also, your customer service is the best.  I could always reach you by email or phone.  I will tell everyone I know about this fantastic addition.  Keep up the great work, guys! ”

  • “ I have a 2015 S1000RR and was extremely skeptical when I heard about BrenTuning and the power they got out of an ECU flash.  After speaking with the team at BrenTuning, all my hesitations were put to rest and I haven't stop winning first place trophies since! BELIEVE THE HYPE! ”

  • “ Bren and his team did an awesome job on my bmw s1000rr. Went from 179rwhp an 83 rwtq to 206 rwhp and 93rwtq. Customer service was great and I highly recommend them for any of y'all that want to make that power!! ”

  • “ Purchased the tune for my 2015 BMW S1000RR. Was skeptical at first and initially had a bunch of questions. Chris was very patient with me and answered them all. Had some problems after receiving my ecu back and Chris was very helpful in getting all my issues worked out. Bike runs fantastic. Definitely worth it. Thank you again guys for dealing with my questions and taking care of everything before and after the purchase. Fantastic customer service. ”

  • “ After doing some research it was obvious that Brentuning was the best option for tuning of my S1000RR. I wont go into details but after multiple overnighting of parts to me at no additional charge, I'm really impressed and satisfied with the end result and I haven't even tried out my race fuel tune yet! To top if off I received a random care package of goodies from Chris today. The customer service at Brentuning is probably the best I've received from any business I've dealt with. Their email response times are unreal as well, lol. Literally sometimes instantly, kinda weird. lol. I would recommend any and everyone to Brentuning for your S1000RR tuning solution. If anyone has any questions or are hesitant before purchasing, feel free to shoot me a message and I'll help / assist / give you a more detailed opinion on my experience as well. ”

  • “ I have the Bren Tuning ECU flash on my 2015 BMW S1000RR and it is unbelievable how fast this bike is. This tune is the best thing I got for my bikes. I have also did the Bren Tune for my 2014 BMW S1000r for which it just made this bike really nice. Bren Tuning is the best. ”
