Sometimes, the best time to upgrade the accessories is before your new bike leaves the dealer's showroom. Here's the two easiest for the dealer to accommodate you. Lithium Battery- By far the easiest. Before the OEM Lead-Acid Yuasa box is opened and the battery filled with fluid, ask them to upgrade where you pay the difference in retail cost. Tires- If you prefer sport touring tires in lieu of the OEM ST2 dual purpose, now's the time especially if you plan on installing the TPS monitoring system.
I tried asking my dealer to change my tyres before I took delivery but they just told me I’d have to pay for a new set with no discounts
That's because you live in the UK and not Canada. You'd be unlikely to get credit for the OE battery as well. Andy
Really? There's absolutely no reason for your parts manager to refuse the upgrade unless he lacks customer focus. The pre-delivery OEM Yuasa is dry and sealed in the box just like any other he would be ordering from Yuasa. My parts manager just said "Sure" since the box was not opened by the service dept prior to the PDI. Batteries and tires are high turnover items.
Evotech protection stuff, Touratech pegs, GPS and spotlights, Urban kit (worth it) if you want them and then when you get home MRA screen and Iconic screen spacers. Bin off the terrible OEM panniers and get some Givi Trekker Outback units with quick-release scaffolding and a tool box. Get a rear wheel / front wheel socket and job's a good un!
I must admit, 4 years unlimited mileage warranty is a shrewd idea. Not only will that encourage people to feel confident in the bikes but also to use them... which will presumably be good for dealer network servicing revenues. I am pretty happy with my 2017 MTS but I'd be happier still if I had 24 months of factory warranty left... if they would do a shaft-driven bike then I'd be tempted to go for a new one.
