So if we had 2 bikes identical in every way one comes with a slater certificate the other just a good replica…….what is the differenchal in value. Just the figure between the 2 bikes. All opinions welcome.
If you had 2 identical bikes, one with certificate & one without, that only really tells you one is an actual Slater import, the other is not. If everything is the same externally, then it's going to have to be a look inside at the cams & pistons. But since all the parts that went into making a Monty were either already fitted to other models in the range or readily available at the time, ( some Mk1's became Mk2's just by changing the fairing & seat unit, the permutations are many ! ), the only real difference is the £150 Slater certificate. But regardless of if all the parts are correct, it's gonna be about how much someone cares about that piece of A4 paper !!
I have an early 1977 Alpino that a previous owner had gone the whole hog & built themselves a Monty copy from it, including cams & pistons. So they are out there !! Thankfully the guy I bought it from had never peeked inside the engine & was unaware of the internal upgrade !! I didn't pay Monty money for the bike, & finding the go faster cams & pistons inside was a pleasant surprise !!
As mentioned earlier in this thread, there's a lot of look-a-likes out there being sold as the genuine article, & depending on a buyer's knowledge of these bikes would dictate the price they'd be prepared to pay ?
It's gonna be whether you have someone who's always wanted one but doesn't know much & will just pay coz it looks the part, or Mr. Knowall who has done his homework, knows every last detail, will pick up on every little issue & kick you in the nuts on the price !! Welcome to the World of Monty !!
Any other additional paperwork you may have for the bike is always helpful though.
