BMW R 1250 GS bike launched at Rs. 20.45 lakh

08 Jul 2021: BMW R 1250 GS bike launched at Rs. 20.45 lakh

BMW Motorrad India has launched the all-new R 1250 GS motorbike in India. It has been priced starting at Rs. 20.45 lakh and is offered in two variants of R 1250 GS Pro and R 1250 GS Adventure Pro. The duo arrives via the Completely Built Up (CBU) route and runs on a BS6-compliant 1,254cc engine linked to a 6-speed gearbox. Here’s our roundup.

Design: The bikes house an all-LED lighting setup

The BMW R 1250 GS Pro and Adventure Pro feature an aggressive design with a sloping fuel tank, an upswept exhaust, and an adjustable transparent windscreen. They also sport a full-LED lighting setup, a TFT color display with support for Bluetooth connectivity, and ride on 19-inch front and 17-inch rear wheels. The vehicles are available in Style Triple Black and Style Rallye color options.

Fact: A 134hp, 1,254cc engine fuels the motorcycles

The BMW R 1250 GS Pro and Adventure Pro draw power from a 1,254cc, air/liquid-cooled, flat-twin engine that is tuned to make 134hp of power at 7,750rpm and 143Nm of peak torque at 6,250rpm. Transmission duties are handled by a 6-speed gearbox.

Safety: Disc brakes are offered for the rider’s safety

The BMW R 1250 GS Pro and Adventure Pro are equipped with disc brakes on both the wheels, along with ABS Pro, traction control and hill start control. They also offer three riding modes: Eco, Road, and Rain. Suspension duties are taken care of by a central spring strut on the front and a single-sided swing arm with BMW Paralever on the rear end.

Fact: BMW R 1250 GS Pro, Adventure Pro: Pricing and availability

The BMW R 1250 GS motorbike carries a price-tag of Rs. 20.45 lakh for the GS Pro model and Rs. 22.40 lakh for the GS Adventure Pro variant (both prices, ex-showroom). A limited-run ’40 Years GS’ edition is also expected to arrive in India.

IPHONE 13, 13 PRO, 13 PRO MAX, AND 13 MINI WILL BE THE 2021 IPHONE, SAY APPLE SUPPLIERS

In not so surprising news, the 2021 iPhone models will be called the iPhone 13, iPhone 13 Pro, iPhone 13 Pro Max, and iPhone 13 mini. According to Economic Daily News, Apple is going to follow last year’s naming convention to name this year’s iPhone model. This may not seem like a big thing, but it paints a picture of what Apple has planned for this year’s iPhone. iPhone 13 means Apple is not going to stray away from the increasing order of numbers for the iPhone anytime soon.

Economic Daily News has cited supply chains to report that the 2021 iPhone would be called the iPhone 13. The iPhone 13 will succeed over the iPhone 12, the iPhone 13 Pro will take things forward from the iPhone 12 Pro, the iPhone 12 Pro Max will have the iPhone 13 Pro Max as the successor, and the iPhone 13 mini will be the successor to the iPhone 12 mini. The “mini” model is specifically interesting because Apple is moving ahead with it this year despite not having good luck with the sales of the cheapest and smallest iPhone model from last year’s series.

Foxconn (Hon Hai) is going to be a major manufacturer of the iPhone 13 series. In addition to manufacturing the iPhone 13 mini, Foxconn is in the process of fulfilling orders for the iPhone 13, the iPhone 13 Pro, and the iPhone 13 Pro Max. Apple has other manufacturers, as well, for the iPhone 13 series. Pegatron, the Taiwanese manufacturer of the iPhone, is back to business after being put on probation last year for violating Apple’s code of conduct for suppliers by asking students to work overtime and night shifts.

The reason why the name iPhone 13 is a bigger deal than you think is the belief of people in triskaidekaphobia, which is the fear of the number 13. According to Macrumors, a recent survey showed one out of five iPhone and iPad users are not in favour of the iPhone 13 as the name for the next iPhone model. At the same time, 38 per cent of the participants recommended Apple should drop these numbers altogether and go for names that have the corresponding year of launch in them. For example, iPhone 2021 should be the name for this year’s iPhone. It makes sense to go with the easy nomenclature here, but Apple is unlikely to heed this.

Besides iPhone 13, this year’s iPhone may also be known as iPhone 12S, according to previous rumours. That belief stems from the fact that Apple has launched “S” models previously, but that is only to denote smaller upgrades in the iPhone over its previous generation. Notably, Apple did not launch iPhone 11S because last year’s iPhone brought a radical design change. Since this year’s iPhone is likely to undergo incremental upgrades over the iPhone 12, some rumours suggested it will end up being launched as the iPhone 12S. The iPhone this year is likely to have a bigger camera, a 120Hz ProMotion AMOLED display, and a better processor.
