In 1976, Honda implemented significant modifications to the 125s cylinder head assembly, transitioning from a single-unit design to a two-piece configuration.
While retaining the cylinder's fundamental architecture, engineers enlarged the bore diameter from 56mm to 56.5mm, resulting in increased displacement from 122cc to 124cc.
This revised 56.5mm cylinder assembly, introduced with the 1976 model year updates, maintains complete compatibility with earlier 125s motorcycles despite these technical enhancements.

Perfect Squeaky Toy for My Exes Deranged Dog
Color: Multicolor, Color: Multicolor
My ex-beau and I are still friendly and we exchange Christmas presents. This year, I wanted to make sure that his utterly nutty and completely bonkers Aussie, Diego, got a new toy so that he has added enrichment in his enclosure. Diego really enjoyed this toy! A perfect size for him and a loud squeaker, which my ex will undoubtedly appreciate being squeaked non-stop while he is trying to game with his various assortment of video game people. Worth every penny. Diego’s smiling face is proof of his delight in his adorable Slothicorn. Squeak away, Diego! Squeak away!

Worth it!
Color: Llama
Wanted to keep this for myself! Made well, size is perfect for a 90 pound pup, durable enough for a non chewer (she cleans their fur but doesn’t chew anymore). Durable enough that has been left outside during Summer storms and washed/dryed a couple times already (I use a laundry bag) and still has its adorable shape. Great value for the money, though I might need to buy another one for myself! *^_^*

Our Doodle's Fav Toy
Color: Multicolor
The first slothicorn toy that we received had a broken squeaker. We were able to quickly and easily get a replacement and send the broken one back. This is one of my pup's favorite toys, although I don't think the horn will last long-- it's the part she likes to chew on the most! At 5lbs, the toy is the same size as my Goldendoodle puppy. I think the toy is overpriced when not on sale (I got on Black Friday promo), so I would encourage waiting for a price drop before purchasing or locating another option that's affordable.
