Right Jay, as I've mentioned, I'm running the Cobra trike tire, and I don't feel that much improvement over the BT45 (rear) I was running, so I will probably give the MPA (rear) a try next, see if I can get a 'feel'. I'd like to get some feedback from someone who has run either the MPA or BT, then the Cobra. Difficult to get feedback from the Cobra since it hasn't been available for lots of miles yet.
My first tire was the MPA. Note: I had Traxxxion Ak-20 cartridges installed along with springs within 1000 miles of being triked. I found the MPA buzzy and in the Arkansas twisties it wanted to "skitter" when pushed thru a hard turn. Same for the BT-45 I used next. Both tires rode very hard and I could feel every little fault in the road surface. I used BT-45's until I purchased my first Avon Cobra Trike.
The difference was night and day. The front felt planted in all situations, rode much smoother, and holds a line thru a hard twisty like it is glued to the road. Will never use anything else unless someone comes up with a better mousetrap.
Keep in mind that here where I live we scrub front tires off quickly with average mileage only 11-13k miles if we stay local. That applies to all tires; MPA, BT-45 and Avon Cobra Trike. I understand that in flat country these tires are running 20-30k miles routinely. However, I'll give up the mileage for living and riding where I do every day. YMMV
