The nicest team you could possibly ask for. They respond to questions quickly, professionally, and with great kindness. I will definitely continue buying from them in the future whenever I need anything they offer. Thank you very much!
The item I received was perfect. Great parts replacement. The service was beyond great! Helped me make sure I got the right part and when shipped to go USA, helped greatly getting cleared with dumb customs. Would do business again!
Great quality if parts, aftersales service is impeccable. Will do business again soon.
These are the second set of fork tubes I’ve bought from msliders. They are good quality and fit with no problems.
I got caught with customs duty on this set but not on the first set I bought. They were still a good bit cheaper than ones I could find in the UK. I would definitely buy from them again.
Super service
Very good service, good quality, reliable and trustworthy experience.
The pipe completely transformed my K1300 from a vacuum cleaner to a fire breathing monster. Easy diy fitment with all fittings etc. took about 10min to fit. Would recommend.
Good
Has a great sound, but had to remove the DB-killer to hear the difference from original, but then I can just put it back when going to check with authorities :)
Happy with the product.

I'm so glad someone makes tubes for this old bike. Thank you from America
