I used this on a Honda CB360 after the rebuild I did on the original still weeped fluid. I used the original cap and it blends in with the bike well. Lever is a little loose but for the price it's been good so far. I haven't tried a Honda lever to see if it addresses these issues but after a couple months it's still working.

Why can’t we have the brake light switch mount

An excellent replacement part for old model motorcycle. ( in my case, a CB400F 1977). Cheaper than rebuilding, it’s a bolt on and fill with brake fluid, bleed air and ride!The new part does not have the warning information on the cap, but I used the original cap which screwed on, no problem. Decent quality for the price.

Came when stated, and works well on the 1978 CB750F. Bolted right on, and bled right up. No provision for brake light swith however, so I'm replacing the banjo bolt with one that is switched

Installed on my 1974 cb750 with dual front brakes. Works good so far. No leaks.

Installed this with brand new lines on a refurbished goldwing, after install and bleeding, everything seemed good. Overnight the brake fluid dripped out of the seal that surrounds the plunger where the lever presses on it. Dripping down and damaging the paint (DOT 4 brake fluid is glycol based and will damage paint), so thanks to this crappy part the paint is now buggered and I need a new master cylinder. Hard enough to find reproduction parts for an old motorcycle that resemble the original, and now they are absolute garbage... dunno if its even worth trying to fix it or just buy a better one. Don't buy
