    We sell Pazzo's and have them in stock. Yes the Pazzo levers are very high quality products ...but no Pazzo lever has bearings in it. The Pazzo levers use plain brass bushing inserts (and nothing wrong with that). But If you want levers with roller bearings in them then you need to go to the top end of the market... to products like the Titax levers used in MotoGP....that we also sell.

    Every brake and clutch master cylinder and perch requires a different design of perch adapter. To correctly design a lever you need a sample of every master cylinder and the bike so that you can check the brake lever allows the piston to fully return back past the compensating valve. You also need to check you get a full clutch throw and release although on the clutch side this is not so much a safety issue as a quality and performance issue.

    The biggest problem I have seen with some of the cheaper after market adjustable levers is that made in Asia is that the companies that make them simply don't have access to a wide range of the larger European or Japanese bikes to test their products on, and as result you get issues like this http://www.gixxer.com/forums/showthread.php?t=274298

    When brakes lock up due to the compensating valve not being able to do it's job of dealing with fluid expansion, they do it a lot more suddenly than you would think. I had it happen in a race car many years ago when someone inadvertently swapped the clutch and brake cylinder push rods over. I've also seen an incorrectly installed brake lever on a bike encounter the same problem and the rider flipped over the front wheel, which locked solid on the front straight at Hampton Downs earlier this year about 50m in front of me. (California Superbike training day). Luckily she didn't hit any road side furniture and she only broke her collar bone - and no I didn't install the lever!

    Levers that do not pass industry design, testing and manufacturing standards are potentially dangerous. While someone may discover X brand of levers works well on Y bike. This provides no guarantee that their levers for Z bike will be correctly designed for another model of bike. Or it could be that they work fine on adjustment position 4 but are potentially lethal on adjustment position 3.

    When you design and build a good product you are proud of it and you put your name on it. You hope that the quality of your product will then make your brand name a valuable and free marketing tool. Some where along the line of reasoning you have to ask the question, why wouldn't a manufacturer stamp their name on their product?

    Come on guys it's your life we are talking about. A $100 helmet is suitable for a $100 head. The trouble with explaining this, is that a $100 head has no way of comprehending the ramifications.

    Yes I do have a vested interest in selling branded safety products - but I could just as easily sell Cordura and cheap non branded levers.

    BTW we do elect to sell some non brand name parts - but they aren't critical safety items.

    I fully agree with you and that Is why I changed my post as to were I believe you could getthese levers from that are decent,

    Yes Trademe ones are probably very dodgy and I should have wrote what I said in a better way,

    I will tell you the name of my brand when the packet turns up I forgot the name it does come in a proper box and has a name etc these ones come from White's they are a good lever, They are just a cheaper version also I stand corrected about the bearing I have no problem with people selling quality parts and I am not trying to take that buisiness away from you as that is against my morals on things, I am just stating the levers whites bring in are a good lever for the price you pay if you want to run something slightly cheaper.


    Please do not take me the wrong way I am not meaning to upset you or take any buisness away

    No problem.

    You help provide a valuable well balanced and well reasoned discussion.

    The neat thing is that there are a variety of good quality options out there to choose from (as well as the other stuff) and the competition makes business fun and challenging as well as benefiting every motorcyclist.


    Look forward to catching up sometime.

    Cheers mate,

    I just wanted to clear that incase anyone looking in to this discussion thought I was trying to be a prick.
    I like how there are so many brands out there but would advise people like in my very first post to get them through a proper dealer like whites or someone asthen also if you do have problems with them you can report it to them and they can then have the problem ammended straight away by either removing the product from sale or similar (if it is a serius fault)

    Trademe is a good place for picking bikes up but I would not buy these levers through there but the ones I use are a knock off 100% I admit that but I brought myne through my Sponsor PFR Motorcycles and I know he got them through White's for me that way I know if they were to be bad fitting and dangerous I could report them back to White's themselves but I have to say I am impressed with them they are more o Bling OEM lever than anything else they do have a fair ammount of detail on them tho might have to get some pictures for you guys

    Cheers,

    Hmmm, how to know if the actuator pin seat is set far enough back the allow correct working of the piston/valve? a) Known product or b) trial and error? ... I'm keen to give things a go but surprise endo... ummmm

    To be honest I first thought you were scaremongering but reading again got me very interested in my front brakes!

    The cylinder (through actuator pin) is partially compressed when the lever is installed. I know this because I ran out to the shed and pulled it on and off about eight times checking. The truth of the matter is I 'll only know if it's a problem when it becomes one… under load, at speed. Bugger.

    Cheers for the post dude.

    Yep, been there done that! Standing in the middle of the track next to your bike as the National Superbike field fly out of the preceding corner towards you is not the place you want to find out why that lever was so cheap, but find out I did. Gawd I hate bike racing.

    WARNING!

    What you describe is not good. The pin MUST NOT compress the piston when it is installed. There should always be free play in the lever before the pin begins to compress the piston. All brake master cylinders/lever mechanisms are designed from the factory with some free play. Without free play you have no way of knowing whether the piston is returning past the point where it FULLY uncovers the compensating valve. Riding it to discover if it is safe is not a good idea. I have never ever seen a brake system from a factory that does not have some very small amount of free play in the lever for safety.

    It may be fine on one day but the next day things metal/pads/seals/brake lines may have moved/expanded 0.01 mm and it may not be safe.

    You should get this checked by an experienced mechanic immediately. I would suggest that you ask them to look at grinding down that pin so you have some free play or bin those levers.

    As per my previous posts in this thread I declare an vested interest in this topic.

    Yip you dont want it compressing allright also be very careful if it is ground because you could also weaken it causing more problems
