I've owned two Gen2 Street Scramblers, which weigh about the same as the ST and the brakes are excellent with enough stopping power to lock the front with two fingers. I never rode a Gen1 but most reviews of the later model remark on the big improvement in braking. The 2nd Gen went to a 4 pot Brembo caliper on the front from a 2 pot Nissin. My ZZR has two four pot Nissins on the front which lack for nothing. It's the extra pots that count, not the name. Long gone are the days when manufacturers could put a sticker on the forks stating the brakes are crap in the wet!
Hopefully when the bits arrive and I've fitted the Brembo 4-pot + floating disc I will be able to confirm the improvement in braking.
I'm fitting the Honda (Nissen) 3 piston and floating disc (ebc) next week. I'm hoping the standard master cylinder will be appropriate. If not, what are my options based on experience gained here? I have a 14mm from a 955i Sprint in the shed but I'm guessing this maybe less than ideal.
Hi, i have fitted a Nissin 3 pot caliper from a Honda cb 1000 plus a 14mm master cylinder also from a Honda.The caliper was a direct fit no bracket needed.Simple work. good luck.
Thanks for the encouragement Iven. A couple of questions if I may. Clearly you used the 14mm master cylinder as the stock (11mm from memory?) was not ideal? What is the difference in lever travel? Any other comments regarding feel/performance? I have a 14mm Triumph master cylinder in the shed and I have a repair kit on the way.
Hi,it was difficult to bleed the Caliper as it was designed for the dual braking system on the Honda,the caliper i purchased on e-bay was brand new and had been converted for use.Now the lever has very little travel,great for my liking. i also fitted HBC brake pads.I am 72 now with a serious back issue but when i can i enjoy the bike immensely, i have also drilled out the baffles in the stock exhaust,now has a deeper rich sound.Hope this is of use.Pete.
Thanks for replying Pete and your help is very welcome my friend. I too prefer a lever with little movement so I will prepare my 14mm master cylinder for use. I have V&H silencers (no baffles) and have removed the catalytic converter and you are right, sounds much better! Removing the airbox 'snorkel' and fitting a DNA air filter have added to the joy in my ears Thanks again Pete, I'll let you know how it all goes.
Hi again,have you considered going one tooth up on the front sprocket,makes the gearing a little longer lowers the revs when cruising,or two teeth smaller on the rear.Also i have fitted a Free Spirits air filter,expensive and doesn't really make a noticeable difference to performance but looks good.Cheers ,Pete.
I have standard gearing. I have thought about t as she is developing over 70bhp at the crank but I like it as it is to be honest. To be honest 70bhp is not a massive figure. I don't take her over the ton but getting there is fun. Also she pulls in any gear so very easy to ride. Regarding power, it is the cam that is the game changer. There are 2 available at the time of writing from TEC. I wanted the torque AND for her to rev strongly to the rev limiter so went for the stage 1. The decat (mine is the free spirits) and the DNA filter sharpens everything up and taking the baffles out makes everything feel special. The pipe and airbox modifications compliment the cam change. I have not had any issues with clutch cooking and my economy is still in the mid 60's (imperial gallon) on a run. These Gen1 Street Twins are a beautiful alrounder once the engine, suspension and brakes are slightly improved. Triumph of course knew this. That is why the gen 2 appeared!
Hi. i just found this thread as I'm looking for info on upgrading my brake setup as well. How do you like your upgrades? And can you share which parts you used? Hi I just found this thread as I'm looking up how to improve my brake set up as well. how do you like your upgrades? Also, what is the adaptor for on the caliper? Thanks
@Lhunt73 Really need to start your own thread as hijacking someone else's never gets much attention. Welcome to the family though.
I'm offering a pretty straightforward brake upgrade for the 1st generation Street Twin, with the 2-pot caliper. It consists of a Brembo 4-pot caliper and adapter bracket supplied by Freespirits. It IS compatible with the original master cylinder (says so in their blurb). If you google their website you will see how expensive these are. I'm asking £95 plus p&p (well below half price). You'll find a pic and more info in the 'for sale' section.
