Vector typhoon is the most solid version of stealth bomber type frames. Beautiful welds, thick gauge of metal, structural supports where needed. Just made right and I really understood this when I tried to cheap out and replace my swingarm with the one distributed by em3ev. Welds looked half complete, steel thinner and of less quality, which made me scrap it and order the right swingarm from vector. I wouldn’t not trust my life with em3ev swingarm. The dropouts didn’t even line up and when you are pushing 30Kw+ with regen, can’t rely on cheap suppliers. Go with vector, solid product, great support and so much fun to ride.
