i bought my bike with the case saver bolts broken. now that im having my motor rebuilt im fixing that too and dont know what case saver to get because i do not want to do this again. and fairly inexpensive. but if it has survived several chain snaps im willing to give it a shot.

The problem with aluminum case savers is that they can break & than they can still break your cases. The UPP's being polyurethane will do a much better job at preventing case damage. That being said I ran my R from 1990 until 2012 with the same engine & no case saver because in 1989 I snapped a chain & lost both mounts. The point is anything can happen but if you get good quality parts like DID chains & Sunstar sprockets & always make sure the chain is set right & lubed than you shouldn't have to worry about it to much.

Proper chain and sprocket maintenance is key. The upp may not be as flashy as others, but it works in a way that no aluminum case saver can. Once it is in place it will absorb the chain energy if the chain does break. It also will not move or cause any of the case saver bolt holes to snap.

To be Clear; I am perfectly fine with the OP purchasing the Case saver he chooses, however I am not fine with the misinformation.

Hundreds and hundreds of BDT Case Savers sold; a few lost chains, and NO case damage that I am aware of or seen; again a lot of misinformation. Assumptions + more assumptions that "the problem with aluminum case savers" & "that no aluminum case saver can" is based on other designs, and not on a single direct experience with a BDT Case Saver.

Regardless of the Case Saver used, a derailed or lost Chain is more about 'Aligned', 'Guidance' & 'Track' than "p
roper chain and sprocket maintenance"...while yes it is important to properly maintain the complete drive -chain unit; it is more important to keep the Chain Aligned, Guided & Tracked....if you do all these Three; you will almost NEVER derail or have a lost Chain, or Broken Cases regardless of Case Saver.

The Only way is to run a 'Chain Guide' on our ATC250R's & TRX250R's...the attached Picture shows a BDT Swingarm + Chain Guide in Place on a customers Race Trike. Just like the MX Bikes.

well now thats different see every one Carlos is ok with the op purchase any case save he wants........ that is incredable that you are allowing him to do that. are you for real ?????????????? there is no miss information here at all. if the chain comes off and the case saver saves the engine then it did its job. not all chains are going to come off the same some snap some miss aligned all under simular but not the same load. what ever a BDT is not much different then many other aluminum case saves. but we all know that you will say hours of R & D on your specialy designed case saver. thats bull crap its trial and error. you mocked 1 up to fit and now you sell them. the upp is a better application than others there is less chance for case damage due to a chain failure. pop that pimple between your shoulders and show others respect. this is a forum for all not 1 to govern no one elected you to over rule. do me a favor and correct me spelling errors and all that mis pronunciation with my alliterate ass.

The R&D on Carlos's case saver consists of looking at the original pumashine case saver and stealing the design. Then selling it as an original bdt design. I'll stick with the upp case saver thank you.

^^^& what does that pic have to do with case savers? Your bdt case saver won the race for you that day?
Agreed, not much, a Case Saver alone is not going to WIN a Race, however; it can make you lose one.

David Ham WON 5 different Race Series in AZ & CA through 2018-2019 Including 3 hour Desert Race Series aboard two Different BDT Engine Built Trikes, that's over 36 Races, more than anyone else, lost a few chains, uses a BDT Case Saver, Broken or Damaged cases; ZERO....needles to say Dave is one of the top Trike racers and awesome rider.

I have! The desert 100 in Oregon. 100 mile trail race on very rough terrain. I did it on my 1996 CR250 not a trx250r, but in the entire time I did not throw a chain. I have in the 30 years of riding ATV'S and dirt bikes had 3 chains come off and 2 of the 3 they broke the case saver bolt holes. I had aluminum case savers both times. I do not use cheap chains or cheap sprockets either. Proper maintenance is vital and second to that is a case saver that will not allow the chain to wad up around the counter sprocket. Upp case savers accomplish that aluminum case savers do not.

Yeah pretty cool huh. I had a blast and finished 3rd out of over 40 riders in my class. I also participated in a 24 hour team endurance race which consist of completing as many 20+ mile laps as you can in 24 hours. Several times me and 3 other fellas competed in events like that. We always placed in the top 5 in our class. We felt we were doing very well for ourselves. I can't ever remember anyone throwing a chain. And best of all nobody I have ever known or seen is running ant bdt crap! I suppose you have done better and feel more important because you have a bunch of shiny bdt stuff on your R. Well bud I gotta tell you that no matter how long you polish a turd it is still a turd. I can't wait to read your incoherent and illegible come back lol
